You can only manually select your focus point when you are in the creative zone. You don't really have to do anything in the creative zone if you put the camera on the "P" so you still have a virtually auto mode in the creative zone.
Yep, get out of the "basic zone", auto programs, and into the "creative zone", manually controlled auto settings. Then just sit in a room taking pictures of whatever while you tweak every setting. It's digital so you can take 1000 pics of nothing just to see what all of the settings do to the pics if you want. You'll learn a ton and get better pics as a result.
