Couldn't you contact the Russian embassy to have your visa reissued?
As far as passport protection, I use a small ziplock type bag for my passport. It's pretty thick plastic, not like a sandwich bag or anything, and I can't remember where I got it from, I just remember seeing it and thinking it would be a good protector for my passport. However, it did break at the bottom, so I'm in the market for a new passport protector too. I'll probably just go with the sandwich bag next time. Cheap and effective. And, oh yeah.... it's waterproof!
As long as your damaged passport is somewhat legible, the visas in it should be fine. Ask the passport office to return your old passport (there will probably be a hole punched through it.) Visas are typically accepted even in an expired passport.
I know that is is okay for US visas.
Since you already have the Russian visa, I don't see why they wouldn't put a new one in your new passport (try to send them the old one too). Being Russia, I'm sure they will charge you...
