Hi HD,
A brave soul you are!
Vnukovo is a magical place. Get your Russian Visa before you go otherwise 3 hours waiting in a Cirrus is not much fun, as they will make you wait on board and disappear with your passports. It’s much nicer waiting on a business jet with a loo and bottle of champers!
If you are unable to display meters on a PFD, I am guessing you have a glass cockpit, otherwise make up a chart for converting meters into feet. Try to park at Vnukovo 1 and you should make the first turning for it, otherwise you will spend the day taxiing there!
Not sure if they have AVGAS, but if they do bring a couple of cans of beer. Not for you but for the refuelers, will help with West / East Relations! Also get some roubles, $'s are no good. For your departure plan for a 1-2 possibly 3 hour delay there may be a presidential flight!
Have a good flight!
