Some had reuse metal gaskets with no prob at all. I would never tho..
Rings should be renew them again.
Have you install them dot or letter up side?
I dont see why you want to boost an engine that shows some probs.You may do more damage mate. Its better to investigate fast what causing your oil consuption. Then you can boost it safely enough.

I think the best thing would be to strip down the engine and look for the problem.Its a hassle but def worth it if you want to pinpoint the exact issue.
Hope you sort out your problem soon.
