Me personally, if the wisdom tooth is causing problems, get it pulled. As for the braces, that's something that a dentist or an orthodontist needs to make a judgement call on. I do believe that there are braces for older people that are hardly visible at all if you're worried about cosmetics.
I would also get your bite checked out by another dentist and see if it can be corrected. In fact, I'm surprised that you're not complaining about pain on that side of the mouth, because typically a bite that's off can at times be rather painful because of extra pressure.
If it was me, I get the wisdom tooth pulled and the bite corrected, especially the bite.
