The brief list (in Russian) of cargoes of Progress M-64 cargo ship has been published on http://www.federalspace.ru/NewsDoSele.asp?NEWSID=3350
My short translation:
Progress M-64 mass at launch - 7056 kg
Fuel in tanks of the Integrated Propulsion System (KDU) - 880 kg
Fuel in tanks of the Refueling System (SD) - 350 kg
Gases in balloons of the Oxygen Transfer Equipment (SrPK) - 50 kg
(oxygen - 29 kg, air - 21 kg)
Potable water in tanks of Rodnik system - 420 kg
Equipment in the Cargo Compartment (GrO) - 1292 kg
(for example, new Sokol KV-2 spacesuit for Sergey Volkov and the target for MRM-2 docking)

Thank you anik! Can you say anything about how much fuel the Progress needs for it's mission and how much of the 880 kg could be used for reboost?

This Progress is also bringing Freon to resupply the coolant loops in the Russian air conditioner, following last month's leak.
"Condensate Processing Update: With the SKV-2 air conditioner currently off due to lack of sufficient Freon-218 (to be resupplied by Progress 29P) and SKV-1 out of service for a long time, the air conditioner’s condensate evacuation pumps (NOK) were put into service to support the necessary condensate processing. The setup was tested yesterday, and preliminary indications were that the NOKs operated nominally. The pumps were powered off during crew sleep and were reactivated this morning." -

It is difficult question, because the quantity of fuel, which needs for Progress flight, depends on many factors.
Approximately 270 - 370 kg needs for autonomous flight till docking. Quantity of fuel mainly depends on used scheme of rendezvous with ISS and number of maneuvers.
Approximately 150 - 260 kg needs for autonomous flight after undocking and for the deorbit burn. Quantity of fuel mainly depends on the deorbit mass of cargo ship and altitude of its flight.
Up to approximately 250 kg can be used for the performing of reboosts of ISS orbit. Quantity of fuel mainly depends on result (success/failure) of the first attempt of docking. -

The "bookmark" amount of propellant available from the 880 kg in the service compartment is 250 kg, but your mileage may vary. What is interesting here are two things:
a) Launch mass is barely over 7 tons. This is the lowest mass Progress that I can recall in a very long time. There may be an unusual reason for such a low launch mass, and it may be connected to the fact that ATV has been successfully docked with ISS.
b) Although at the moment, propellant is not really needed aboard ISS, this Progress, despite the low launch mass, is still carrying over 300 kg. I can think of only two reasons for this, both speculative:
1) This represents the amount of propellant required for the small mid thrusters to dock with ISS in the event that the service compartment engines all fail, or
2) to carry a mass even as low as 1200 kg of dry cargo in the "front" of Progress requires 300 kg of mass carried in the mid section to preserve the c/g.
I don't know if either of these is the correct reason, however. -

Further the ascent unit will be transported for the assembly with stages of Soyuz-U rocket. Soyuz-U rocket with the cargo ship will be rolled out to the launch pad no. 5 of the area no. 1 of Baikonur cosmodrome on May 12th.
Images (below) of Progress M-64 preparation to the launch are from RSC Energia website.

According to this very respected poster in the ISS Q&A, at the time of the post the RS was very loaded with fuel, if my info about 6 100 kg capacity in Zarya and 860 kg in Zvezda is correct.
Zarya fuel 1867.3 ox 3365.0 total 5232.3
Zvezda fuel 297.0 ox 572.0 total 869.0
Total fuel 2164.3 ox 3937.0 total 6101.3
Since then I don't think reboosts has been performed by russian segment but attitude control has been done, so not much fuel usage.
Since then one Progress(?), one ATV(880 kg), and now again a Progress(350 kg).
Can Progress fly without reboost fuel or will Zvezda have to perform reboost in order to prevent the next vehicle undocking with fuel still in its refuel tanks? -

Since December 30th, 2007 two reboosts have been carried out on January 12th and February 28th with the using of Zvezda's engines. -

May 10, 2008, Baikonur launch site, branch office of S.P.Korolev RSC Energia.
At Baikonur launch site the preparations continue for the launch of Progress M-64 cargo vehicle under the International Space Station program.
Orbital module of the Soyuz-U launch vehicle, containing Progress M-64 spacecraft was transported from the spacecraft processing facility for the general integration with LV.

12.05.2008 space rocket to "Soyuz" with the transport cargo ship "progress M-64" are exported to the launching pad
http://www.roscosmos.ru/NewsDoSele.asp?NEWSID=3365 (with photos from Roll Out)
Segodnya in the morning at the spaceport Baikonur is realized removal to the missile takeoff of the space application to "Soyuz" (developer producer "QSKB- progress") with the transport cargo ship "progress M-64" (developer producer RKK "energy" im. S.P.Koroleva). Rocket is established into the launcher ? of 5 areas ? of 1 spaceports.
The solution about the removal RKN to the launching pad was accepted yesterday, on 11 May, in the course of the session of technical direction and state commission, which was taking place herself on the area ? of 254 spaceports.
After the completion of operations on the removal of space rocket to the launching system the calculations of the enterprises Of roskosmosa continued schedule work of the first starting day it is conducted preparation for the general tests RKN, whose beginning is planned to 15:00 Moscow time.
Launching RKN "Soyuz-"Progress M-64 "is planned to 00:22 Moscow time on 15 May of this year.

I wouldn't expect any given it's a Progress launch and they never get any coverage (I keep asking myself why), but seeing RussiaToday seems to have taken over space program reporting, and they seem to be covering it quite thoroughly, perhaps this time it will be different...
Anyone knows something more?

With Progress launches, first we usually hear is via Anik, or someone from the NK forum.

Just wondering, do Progress and manned Soyuz use the same launch complex?

Yes, for now. But they will use two launch complexes simultaneously since 2009. -

The liftoff has occured on-time. The cargo ship is on orbit.
