You are on the right track. Do all of the bearings, dont forget about seals as well. If you can post pics of the rear caliper and the carb issues you have we can better help you and advise on a repair or replace approach.
Buy a good compression tester and test compression as well. It doesnt look like your motor has ever been apart but it wouldn't hurt to do a leakdown test. Search this forum for all of the info you need. Its here.
Welcome aboard. Prepare to surrender your wallet!
