Good morning Jim. Welcome to the GTA. The library is a great place to start, but the search engine here at the GTA is great.
Goo gone is an excellent product for cleaning the barrel. I tie a cleaning patch to a piece of 30# monofilament fishing line with a slipknot and pull it through the barrel from breech to muzzle. Some guys have used string trimmer line for the same purpose,they heat one end to form a small bulge and cut the other end sharp to pierce the patch,either way,it works.
The people here are more than willing to help at anytime and there are no dumb questions,so just feel free to ask anything.
A word of warning,air gunning can be very addictive,so start putting a little money aside because you are going to need it.LOL. good luck and good shooting,snookman
