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.

OP here, any more tips? I slacked off for awhile and I'm finally going hard on it (no homo). I've managed to acquire a few e-books to help me on my way.
