For Anderson, it will be a pretty significant stretch. Good luck with USC!
I simply don't know enough for Pepperdine and UCI to make any comment, but I suppose you'll make a pretty good applicant.
Reason for Anderson as a stretch is you're simply too 'middle-of-the-road' right now. You're in a typical position, with a typical degree (not saying that it was easy, but I assure you that plenty of accountants/accounting majors have applied in earlier rounds and the accounting quota is pretty limited now). Not only that, there are a couple of glaring disadvantages: your age and work experience will play a big role here. Typically, you're looking at 4-5 years of work experience for top b-schools and with only close to 2 years of experience, AdComs will question your reasoning as to why now. In addition, Anderson has a notoriously high average GPA for its admitted students, averaging a 3.5 undergrad for the students from Anderson. At 3.0, you're pretty much at the lowest 10 percentile for its class (by the way, congrats on the fantastic GMAT score!!). These are my reasons for Anderson. I'm not going to talk much about USC since you've already applied - just keep your hopes up!! And as I mentioned, I can't speak for Merage or Graziadio since I know nothing about these programs.
