Go by car. It's rather convenient. First - to Germany and via ferry to Finland (Turku). Then to Helsinki and further to Russia either by ferry or by car. The trip by car from Paris to Moscow will take approx 3 days.

DON'T EVER GO TO RUSSIA THROUGH UKRAINE! Believe me. A side trip through Finland will cost a third the price you'll have to pay to crazy ukranian traffic police.
Consider:
I've had to pay about $700 in total only to go through Ukraine and it took me 2 days to make it to the Russian border.
Ferry will cost about 120 Euro. Besides there is a bridge from Denmark to Scandinavian peninsula so it's possible to cross there by car but it'll cost extra ~3000 km (2-3 days).

The optimal route will be a ferry from Travemunde (Germany) to Helsinki and from there by Car to St. Petersburgh (~150 km). It will take approx. 48 hours, 120 Euros (car + 2 passengers cabin included) plus expences on fuel to reach Moscow (+800 km from St. Petersburg) from Northern Central Europe. I've done that several times and It's my most favourite way of travel.
