The act of massaging your lobes will help with that scarring. Bio oil is great stuff. I use it too. Personally, reading through your story, I'd continue with your oil massages longer and leave stretching for a bit more than just a few weeks until mid Nov to see how things go.
Dead stretching is always a great option as long as your lobes are ready. But taping is ok, better than tapers. If you can get tape around a 4g plug, do it. Personally, I found it very fiddly to do but started using tape at 2g.
Clever got me this far, then tricky got me in
Left lobe- 00g first hole, 2g second hole
Right lobe- 0g
Right helix rim- 14g x3 around top
Right brow- 14g x 2
