I used the Bastien books when I was a kid. Even though I suck at playing the piano, the books themselves were pretty good. There's a series for adults called the Older Beginner Piano Course.

But what sort of music do you want to play? Do you want to be able to play from standard notation? Do you want to play from fake books? Do you want to do the sweet stylings of jazz improve?

Or learn chopstix?

Anyway, I'm sure that in any case you're going to start off in the same place, since you have to get skills like fingering down.
