Welcome to the club. Check out the tutorials on the home page. They should help you out. A good cleaning is the first thing you should do. Keep in mind that these pistols are sensetive to cheap ammo (Wolf.) Stick with CCI or WWB for break in and you should be good to go.
Another thing to keep in mind, if it isn't broken don't try to fix it.
I suggest reading the archive of topics here. Most everything you need to know has already been discussed at length.
