Congratulations on your splendid new MBP and welcome to the world of Mac. May you and your computer both live long and prosper together. You'll really enjoy the MBP, I'm very happy with mine.
Re keyboards, and different ways of doing things, I switched earlier this year (also to a MBP) and love it. A lot of it can be learned by just using the computer, and also feel free to ask questions from people on fora such as MR. I found a file called MacSwitcherTips which I placed on my desktop for handy reference. (I don't have it to hand just now, as I'm back to the world of Windows - not by choice - in the Caucasus).
The important thing to remember is that most of the commands on a Windows keyboard have an equivalent in the Mac world; they may not be identical. You can get the equivalent function of the right click by combining Function and Command keys on the Mac (Command might have a picture of the Apple logo on it) and so on. Just ask if you are not certain.
Cheers and good luck
