All in all, not a bad report. The paint and top are presentable as-is, so I'd enjoy it. The hood on the other hand, do you think you could just paint the hood for now?
Yes, the only way to deal with the rust pimple is to pull the top back. Be prepared to find more. Plus you may find some rust in the rear glass channels. My car had some pin holes there too.
My drivers mirror is in the same condition. Shines up nice, but has some pitting bumps. I'd love to get a new or rechromed one, but as you have noticed, they don't interchange with the RWD cars and cost a small fortune.
