I know about the plenum, seems to be only a requirement in commercial applications where the cabling occupies the same space as HVAC ducting, not residential... at least that's the case in my area, I didn't see anything that indicated otherwise. I also know about the difference with cat5/e/6, they're applications, and their ratings. It's a little more difficult differentiating between good quality cabling and cheap cables not worth choking a man with. But for a residental applications, I think I can pretty much get away with almost anything I buy.
Thanks for the responses, I always figured the jacket colors were arbitrary, but all my previous applications were always temporary. ie, I lived in an cottage and I didn't give a rats ass what I stuffed down the walls. This is the first time I'll be running cabling through the walls on a permanent basis. I wanted to make sure I covered my bases before to buy the cabling.
