LV Soyuz general integration is completed
It happened in MIK-40, so I guess the launch will be from 17P32-6...

I thought Progresses had an orbital lifetime limit of around 6 months, due to corrosion of the propellant lines in the peroxide thruster system?
The peroxide system (СИОС) is used only on the Descent Compartment of Soyuz spaceship. Since there is no Descent Compartment on Progress, there is no peroxide system.
On Soyuz, the problem is not about corrosion. The problem is that H2O2, naturally, transforms itself into O2 and H2O. If the Soyuz stays in orbit for more than 6 months, estimations show that remaining quantity of H2O2 is not sufficient to ensure a safe reentry.
Note that on Soyuz's first version (11F615), the attitude control system of the whole spaceship use H2O2. Since Soyuz T (11F732), the attitude control system uses the same propellant tanks than main engine (SKD).

Are these still Progress M1 vehicles or has the model evolved on since then?
Progress M1 had some very advanced features, but was discontinued due to expense and lack of requirements for the extra prop that it could carry.
The whole M1 did seem a curious evolution as was there ever that strong a need for extra propellant carriage at the cost of dry cargo for ISS.

In the early days of ISS, ATV delivery of prop was not obviously going to happen.

I suspect that's a typo - the launch is a Progress-M, not a Glonass-M.

I believe it is now three minutes until midnight in Moscow, and the launch is scheduled for 45 minutes after midnight, Moscow time.
