I made an Interrail with my best friend on August 2012, we started from Milan -> Zurich -> Munich -> Berlin -> Hamburg -> Copenhagen -> Osnabruck -> Amsterdam -> Frankfurt -> Milan. It's a very unique experience, I recommend you get ready for almost everything and you'll have one of the best time of your life! I see that you are from Finland (I got MAD love and respect for Suomi, one of the most wonderful countries I've ever been), since you can't use Interrail in Russia I recommend you buy some cheap ass flight to some central Europe city and plan the trip from there. If you book hostels you will save A LOT of money, but on the other hand if you don't book hostels you can go wherever you want.
Hope this helped, if you have any question feel free to ask!
