Welcome to the Stovebolt Chevyjen. Your at the right place.
If you will ask your questions in another forum like the General Truck talk or maybe the Engine Driveline you will get more answers and responses. Not everyone visits here in the Welcome Forum.
Most of what you have mentioned can be done with a minimal of tools so don't be afraid to try it. With TWO trucks a good investment would be a shop manual and an assembly manual...and there is an online manual done by a fellow bolter. Here is a link to them
http://chevy.oldcarmanualproject.com/Be sure you have the brake adjuster backed all the way off...then try using two small pry bars/screw drives one on each side. It probably has a groove worn in the drum.
Go for it. This is all about learning our old trucks and you can do it. Make a plan and take your time..... and ask questions of all the pro's hanging out here.
