Don't apply as a junior, that's a dumb move for 99% of applicants in general, nevermind someone with an IA. Not sure what CAA or AA acronyms are, so you'd have to elaborate. I'm saying if you decide to apply as a senior, you should also apply to grad schools in bio or chem (if those are the types of jobs you want). A B.S. in cell and molecular bio will be good for getting a graduate education in that field, not a job. The graduate degree will help with getting a job (even if it is still a mediocre market). By doing so, you become more marketable to a wider set of employers and can say you have a more specialized skillset. You become more desirable as a potential teacher and could even get positions at some colleges with a master's. It just opens more job opportunities. If you just want to get into med school and are willing to reapply/wait to apply, I suggest getting a certification and doing a clinical job if you need money, as you'll be improving your application and earning some cash simultaneously.
I only partially agree with that. I got my degree post-2008, and I had a half dozen friends that graduated with chem/biochem degrees that got decent jobs straight out of UG. In fact, I don't know any chem or biochem majors that didn't either go on to grad school or find a job after UG. They weren't glamorous 6 figure jobs, but I believe all of them were at least 40k, which is at least respectable right out of UG. If we're talking about straight-up bio degrees, that's a different story...
