For the record, I have never taken anatomy (nor do I plan to) and I have been invited to interview at 7 out of the 9 schools I applied to. I feel pretty good about most of those. If you decide not to take anatomy, your DAT scores and GPA will matter even more than normal (I imagine). I got a 22 AA and a 22 TS fyi.
I don't necessarily agree with the statement above that says "when a school says recommend course, it might as well be required." I think that if you have the room in your schedule, you should take the recommended classes (it might be a good idea to take Microbiology though, since you'll have more credit hours, and schools like to see that). I also think you'll be grateful you took them once you're in dental school. I'm also guessing that different schools have different opinions about how important recommended courses are.
Good luck.
