If I buy a Disney annual pass when will I be billed for the first month?

When I went to Great Adventure I could fit on most of the rides there but it was the nitro ride that I did not. I am not very overweight but just slightly. I am 5'8 with long legs ...

I'm meeting a friend tomorrow night after work at about 5pm. I haven't been to the mall in years. I also don't like crowds. will the mall be crowded?...
