Self-taught Spanish

I'm going to teach myself as much as I can about Spanish over the Summer. I have a College Spanish book my brother gave me, and I was wondering if the Teach Yourself Spanish book was any good. It can be found on Amazon, and I've always found their reviews to be horrible. If not, what do you reccomend?

I'm going to practice my Spanish over LiveMocha with Spanish speakers in return for helping them learn English. Does anyone know any other good resources online for learning Spanish or a really good book? I can find a lot on google, but I know someone out there has saved a site he/she thinks is awesome.

i have the teach yourself latin american spanish and it isn't as good as the german one, if that's any measure for you.
