That new and shiny Soyuz pad sure looks good :) Is it that new or just re-painted?

What is it launching?

Pretty good size payload/nose shroud.  My curiosity has been aroused, too.

It is the old launch pad 43/4 for launches of Soyuz-U or Molniya-M rockets in the past. A long time ago it was modernized for launches of Soyuz-2 rockets.

Google Maps image of this launch pad: http://maps.google.com/maps?f=q&hl=en&q=62%C2%B055%2744.06%22N+40%C2%B027%2724.71%22E&ie=UTF8&z=16&ll=62.928859,40.456789&spn=0.004629,0.021501&t=k&om=0

After four-day tests the rocket will be returned to the integration building (MIK) for preparation to the launch of military satellite.

Will this launch use a Fregat upper stage?

In the Russian Launches Schedule there is a rumour about the launchtime, being 22:40 Moscow Summer Time, or pretty close to it (can´t remember that precisely :P). The idea is that it is a Persona satellite.

Launch occurred to-day at 18:31 UTC.
As mentionned above, the payload is reportedly the first Persona electro-optical reconnaissance satellite featuring new technology and a 7-year lifetime:

I have seen several news reports now mention that Soyuz 2-1b has a "more powerful" third stage engine.  The RD-0120 staged combustion Blok I third stage engine is, as I understand it, actually not "more powerful", in terms of thrust, but is much more efficient, in terms of specific impulse.  The information I have says that the old RD-0110 engine produced 30.38 tonnes of thrust at 325 sec ISP while RD-0120 produces 30 tonnes thrust at 359 sec ISP.

IIRC, RD-0124. In Russian news has not seen anything about "more powerful". RIAN writes that the engine has a "high specific performance".

Yes, RD-0124.  Sorry about that typo.
