Blingbling-
First off, I have to agree with the general consensus of most of the previous posters: You will learn enough of the material covered in medical school while you are IN medical school! Take fun courses as much as possible while an undergrad, and feel confident that your required pre-reqs will make you adequately prepared.
However, that being said, I happen to have a better perspective on your question than anyone who has answered yet. Not to disrespect any of the other SDN users, of course, but I happened to take every single one of the courses you mentioned while at CU-Boulder!
I assume that you aren't an MCDB major, otherwise you would have to take half of them. Personally, I disliked both Cell and Molecular, but that was due to teaching styles more than anything. If you must choose one, go with Molecular. A&P are great, but are particularly good as summer courses if you can work it in! I suggest Anatomy in the summer, and Phys in the fall if that works. BioChem was a good course, and I know that a handful of medical schools I have spoken with recommend it. Once again, though, you will be taking this course in medschool, so the preview may or may not be that worthwhile to you.
The bottom line is to take only classes that appeal to you personally. There are enough sh*tty courses to take in college! If you don't like the class, you won't excel, and that will hurt you a great deal. (Believe me on this one!) Good luck, and if you want any suggestions on which profs to take, let me know.
