Don't get too worried by the Community College naysayers - Community College, especially California Community Colleges, can be really great schools, on top of saving you tons in student loans. I've experienced the Dental side of this, which is more or less the same as Med. The only problem you'll run into after having gone to a CC is the few schools that don't like CC credits, such as Tufts for Dental, where it's near impossible to get in after having taken CC classes, but the number of schools that really discriminate against CC's is getting smaller.
The Key to success in professional school applications after having gone to a CC is to really prove yourself after you transfer. For example, if you want to transfer to most UC's from a Community college, you'll need to take a year of bio, and a year of chemistry before you can apply - and since this is a major part of the Health Professional Schools Pre-reqs, you need to be sure to do well in the upper division classes that you take in similar areas once you transfer. I went to Community College and took more or less all of my pre-req classes there, a year of general bio, genetics, ochem, gchem, physics, and once I transferred to UC Irvine I just kicked butt in the upper division classes (which I found easier actually, haha), just to make it so that no one can say that you had it easy at the CC.
When I applied, I did well on the DAT (Dental version of the MCAT), and further proved myself. Although I was given the occasional "well, we would have liked to see you take these lower level classes at a university," it really was a non-issue for the most part. I got into a number of schools, including an Ivy league, and that's after taking all of my pre-reqs at a CC.
Oh, and if you go to a CC, go for two years, finish your GE's, get an IGETC (which says that you don't have to take any more GE at the school you transfer to), take the basic sciences you need to, transfer, and do great where ever you end up. You really won't be able to transfer easily after one year, since most schools want to see that you've taken at least 60 units, and the individual programs (ie. The School of Biology) will want to see that you've taken basic pre-reqs (Bio, GChem).
Good luck, don't stress, and just do your best!
