GPA and MCAT matter most. 2 years at a CC should not really hurt you, but many people also recommend you take some upper-level courses after you transfer to the university; to show you can handle their work as well and you didn't get a high GPA just from going to the CC.
Personally, I would do the CC major that has at least some to most of the basic pre-reqs. That way, you'll have some out of the way at least. If business has that, then sure why not, but if not, don't unless you're truly interested imo. But, I'm only going to be a college freshman as of this fall, so maybe some others who've gone through the process can shed some more light on the subject.
