Hi,
Hope you 'govorit po russki' - those border crossings can be hell without knowledge of the local lingo, oh, and a few marlboro/camel packs plus the odd half bottle of genuine scottish whisky!
Good luck with the weather too. The river Ob can be a brute when it floods... over 40km wide! My polish friend had to turn round at the Urals (ooh err!) thanks to that.
Still, it sounds like you've got it covered. The rest of us can only dream, for now...
