Vivian,
Welcome to diving, and to Scubaboard! You'll enjoy both, I hope.
For your criteria, there's no significant difference between PADI and SSI. I'm a PADI instructor, but I'm also very familiar with SSI. The instructor makes a bigger difference here.
By all means, talk to the instructor before signing up for a class. Walter's list is very thorough, and very good. Beyond the answers you get, ask yourself if you want to spend all this time with this instructor. This is recreational diving, and learning it should be fun, too.
BTW, Cold water does not mean Cold diving. It means a heavier wetsuit, and slightly trickier bouyancy control. No big deal, really.
