I'd suggest, if you're starting with color, to not worry about WB anyway: if you're handy with computers, you can do what you need pretty easily with any post-processing: correction filters are kind of mostly for slide film or the studio, in my book, (just don't be surprised when things look terrible under some old flourescent lights)
I don't think I even own any CC filters anymore, in fact, but then again, most of my color work dropped out years ago, and digital kind of brought it back. (Nice to not have to carry a second body for it, you can just turn on the color.
)
I'd start with negative film, by the way. It's just more exposure-forgiving, and not as generally-inferior to slide film as it once was. One thing to watch out for, though, is that sometimes the quality of processing and printing isn't up to snuff anymore, if you go to certain labs, so, be sure to check out your negs if prints are unsatisfactory. You may still have good images.
