For anyone not following this closely, its a Russian lander, modeled after the Phobos Grunt lander, which is a miniaturized version of the Luna landers.

I'd read that ISRO wants to add an additional smaller rover, specifically in connection with investigation of lunar water that's recently been found.
They say they'll simply trade off mass against other parts of the payload, perhaps making the orbiter smaller.

Was there an orbiter planned as part of this mission? If so, then what was its purpose?

I'm sure ISRO wishes that its GSLV-Mk3 rocket was available for this mission, given the heightened mission demands and compelling interest from the lunar water discovery.

Payloads for Chandrayaan-2 Mission Finalised.

Chandrayaan-2, India's second mission to moon, is being targeted for launch during 2013. Chandrayaan-2 will have an orbiter (satellite), a lander and a rover. Chandrayaan-2 is planned to be launched onboard Geosynchronous Satellite Launch Vehicle (GSLV) from Satish Dhawan Space Centre, Sriharikota. While the lander will be provided by Russia, the orbiter and the rover are being built by ISRO.

The payloads to be flown onboard Chandrayaan-2 (orbiter and rover) have been finalised by a National committee of experts drawn from ISRO centres, academic institutions and R & D laboratories and Chaired by Prof U R Rao, Chairman, Advisory Committee on Space Sciences (ADCOS) and former Chairman of ISRO.

The committee, after detailed deliberations and considering the mission requirements, weight and power available for scientific payloads, has recommended five payloads to be flown on the orbiter of which three are new and two are improved versions of the payloads flown earlier on Chandrayaan-1 orbiter. The committee has also recommended two scientific payloads on the rover of Chandrayaan-2. Inclusion of additional payloads, if possible within the mission constraints, will be considered at a later date following a detailed review.
The five recommended payloads of Chandrayaan-2 orbiter are as follows:

1. Large Area Soft X-ray Spectrometer (CLASS) from ISRO Satellite Centre (ISAC),
    Bangalore and Solar X-ray Monitor (XSM) from Physical Research Laboratory (PRL),
    Ahmedabad for mapping the major elements present on the lunar surface.
2. L and S band Synthetic Aperture Radar (SAR) from Space Applications Centre (SAC),
    Ahmedabad for probing the first few tens of meters of the lunar surface for the
    presence of different constituents including water ice. SAR is expected to provide
    further evidence confirming the presence of water ice below the shadowed regions of
    the moon.
3. Imaging IR Spectrometer (IIRS) from SAC, Ahmedabad for the mapping of lunar
    surface over a wide wavelength range for the study of minerals, water molecules and
    hydroxyl present.
4. Neutral Mass Spectrometer (ChACE2) from Space Physics Laboratory (SPL),
    Thiruvananthapuram to carry out a detailed study of the lunar exosphere.
5. Terrain Mapping Camera2 (TMC2) from SAC, Ahmedabad for preparing a
    three-dimensional map essential for studying the lunar mineralogy and geology.

The two scientific payloads on Chandrayaan-2 rover are:

1. Laser Induced Breakdown Spectroscope (LIBS) from Laboratory for Electro Optic
   Systems (LEOS), Bangalore.
2. Alpha Particle Induced X ray Spectroscope (APIXS) from PRL, Ahmedabad.

Both the instruments are expected to carry out elemental analysis of the lunar surface near the landing site.

Chandrayaan-2 spacecraft weighs about 2,650 kg at lift-off of which the orbiter weight is about 1,400 kg and lander weight is about 1,250 kg. Development of the subsystems of the orbiter and the rover is in progress at ISRO centres in Bangalore, Thiruvananthapuram and Ahmedabad.

It'll be quite interesting to see what lands on the Moon first: Chandrayaan-2 or one of the Google Lunar X Prize contestants.

The probe is slated to launch in 2013, long after China's current Chang'e 2 moon mission ends.
China launched the Chang'e 2 probe on Oct. 1. It reached the moon Wednesday (Oct. 5).
India, meanwhile, approved plans for its Chandrayaan 2 mission in August. But unlike China's new probe, which is an orbiter, Chandrayaan 2 actually includes three vehicles: an orbiter, lander and rover, the Indian Space Research Organisation said.

Race back to the lunar surface is on. Change'3 is scheduled to land around late 2012.

Does it mean all major missions till Chandrayaan-2 will only use indigenous engines? Since the Russian engine has to be examined, will Chandrayaan-2 be delayed?

Yes, it has to be tested on indigenous cryogenic engines, and we’ll only use our engines for future launches, but that is not why there will be a delay. Historically, the Chandrayaan missions are a joint Indo-Soviet mission. The agreement was that the lander [that will descend on the moon] and the (lunar) rover (a robot vehicle) would be provided by the Russians. We wanted to put a smaller rover; it’s something new that we are developing. However, in Russia there was a rethink. They decided they’ll only develop the lander and some instruments related to it. That means India would have to make a bigger rover, a decision taken almost a year ago. There are also preliminary design reviews to be undertaken this year to select which instruments are to be carried onboard the mission. So it’s not only GSLV (engines); there are other reasons for the delay.

Russian sources say that the failure of the Phobos-Grunt mission will impact the Chandrayaan-2 mission, delaying it by 3 years:

http://www.thehindu.com/news/international/article2854134.ece

This is because technologies and systems used in Phobos-Grunt are also present in the Russian lander which is to be used for the Chandrayaan-2 mission, and these will have to be subjected to review.

The Chandrayaan-2 mission was originally scheduled for launch in 2013, but was facing delays due to the 2 consecutive failures of the GSLV. The mission is now expected to be delayed until 2016, due to the failure of Phobos-Grunt.

 On Chandrayaan 2, K. Radhakrishnan said the Indo-Russian Joint Venture on a GSLV launch vehicle would be on an Indian rover and Russian landing station. But there could be some delay in the latter as there was a ‘major’ review of Russian space programme following a recent failed mission.

“The orbiter is in very good shape (and the launch could be) possibly by 2014. When exactly the landing module is made available is to be seen but we are ready for 2014,” K. Radhakrishnan, flanked by ISRO’s top scientists said at a press conference here.

IIRC Luna-Resurs (Lander/Rover) and Chandrayaan 2 (Orbiter) are now separate missions.  ISRO can launch Chandrayaan 2 whenever they are ready to.

Initially,the mission consisted of indian orbiter and russian lander + rover. Later, it was indian orbiter + mini-rover and russian lander. I think this is still the case. The slides that I provided is from july 2012 and  L-R clearly mentions India in the bracket. This slide is fron Jan 2011

According to Anatoly Zak, Luna-Resurs was split up during the post-Fobos-Grunt re-evaluations.  AIUI, the current plan is to launch Luna-Resurs sometime in 2017 (depending on how well Luna-Glob 1 & 2 do) on a Soyuz 2-1b w/Fregat.
