The one-to-one was a good investment, congrats!
My only initial advice to you on your new purchase is this:
1. Read the three stickies in this subforum -- they all have good advice for new Mac people, and dispel a lot of myths.
2. Unless you have a specific need, don't run off to load up the thing with third-party software right away -- take some time, discover what's already on that machine. You will be surprised.
3. Learn some of the new terminology, like Dock and Finder. This will REALLY help in articulating what questions you have later. Also, be sure to list (preferably in your little "bio" on the side) your Mac specs -- saves a HUGE amount of time when answering questions.
Mac 101 and
Switch 101 will be big helps in this department, have a look at them.
