1. Don't sweat it about doing the "right thing" with it.
2. Don't put $ into refinishing until you get a chance give it a test ride. The kink might be a big deal, but then again, it might not. It will take some $ and effort to get what you need to make it rideable, but you can either re-use, or recover expenses on most of it if turns out you can't use the frame.
3. If test riding proves it to be unsatisfactory, then consider whether you feel like trying to have it fixed or not - unless the idea of riding it like that is more than you can tolerate. In any event, I'd not pour cash into it until I removed that doubt.
