On your drums don't turn them if you don't have to. They are not available new and anything you turn off reduces their life. I'd only have them checked for running true and turn the lip if any off. Don't cut the braking surface if they look good and are true already.
You may find replacement springs and adjusters at the auto parts store. 3B might have some part numbers for you, or he has probably provided them to someone else already if you search the forum a little.
You DO need the adjusters to work, they are very necessary.
