A few pointers:
get an international driving permit. Even if it may be legally possible to travel with the driver's license you have, having a document translated in several foreign languages (including Russian) will certainly help.
make sure your car insurance covers all the countries you plan to visit. If you plan go visit countries outside of the Green card area, you may need to buy additional insurance for these contries.
make sure you have documents which allow you to drive your car with you. Typically, that would be the proof of ownership. Translating these documents to local languages where you don't expect people to speak English (read: Russia) is also advised.

There is a customs union between Russia, Belarus, Kazakhstan, Kyrgyzstan as well as Armenia (the latter being not relevant to your case). This is how you proceed:
If crossing internal borders of customs union member states, always have your (original, stamped) customs declaration copy at hand. IDP is not required in Russia, if you have an EU driving license, but might be handy, especially in the 'more corrupt' countries.
