Very nice looking blastos..
Take the time to read the manual. I got the T1i in the summer and haven't gone all the way through it yet.
Get a large SD card for taking lots of pics as practice makes perfect.
Go on ebay and find a remote for taking pictures. If you use a tripod and line up it will really help with camera shake (I have to get one myself- I borrowed my moms when doing pics at her place and it made a good difference).
Experiment. You never know what you can do until you try. I personally love shooting the stars.
Above all else, have fun with it.
