Shoes can be relined pretty cheap.
Drums you'll have to look for good used or NOS. Post a wanted ad in the Swap Meet section.
As a general rule don't turn the drums if you can avoid it, no need to waste good material on hard to get drums.
If they are out of round or extremely worn/grooved then you'll have to, but if they are round and not to bad just put new shoes in and give them some time to seat before expecting them to work perfectly/quickly.
