Learning Russian

My summer project is to learn a bit of Russian. Could you guys direct me to some good guides and books to help me begin? Also, any tips to help me stray from making mistakes would be appreciated. I'm looking to read and write rather than be extremely proficient at conversation if that means anything.

I especially need a good introductory book, as I'll be leaving for a trip in a few days and I hope to study during it.

The important thing about learning Russian is not asking any Russians on the Internet to help you. It seems they really don't like it when anyone not from former Soviet states learns their language.
