Well, start going through and resolving those items. You have a misfire, O2 codes, and several other things. Off the cuff I'd say check to see if you have cracked exhaust manifolds and do a compression check. You may have a dead cylinder and need a motor. Hopefully not.

I would go back and check your work. Make sure the harness isn't dangling and melted against the exhaust. Connection could be bad well. Also if you went too cheap on 02s that could be an issue.

Oil on the plug might not be rings. Depending on where it is (on the plug tip, or all over the plug body, it could be a bad seal at the plug on the valve cover. Solution there is to replace the valve covers (can't get the seal separately).

As for rings, if you tear into that motor before you do compression and leakdown tests, you're crazy. Diagnose it first, then start replacing things. Throwing parts at it is an expensive hobby.
