I decided to leave them be for now. Actually today I got the bike ready for winter. Since for the forseable future it really won't break much above 40 degrees.
As far as the bolts, the rear ones seem like they will come off somewhat easily when I decide to deal with them. After playing with them the other night they actually got slightly loose and I needed to tighten them today. The rusted OEM ones look like trouble. They really look like they will strip out before they sheer.
I am learning to pick my battles, and not create issues.
