Let me see if I can answer your questions...

First, as I mentioned earlier, if you are indeed bending your hangers, you should replace them and NOT straighten them. Obviously there is some sort of problem, so taking it to your LBS is something that I would definitely recommend. Perhaps changing your crank would give you the gearing that would be more beneficial for you and your bike... but it's still something that should be checked just in case.

Secondly, if your chain line is off there are a few options. It can be off because the frame itself is off(and happens more than one would believe). It can also be something very minor... perhaps a spacer behind your cassette.But regardless of what the problem is, it sounds like this is something that should be investigated. You obviously have a nice bike, and it's worth the extra time to figure out what the problem might be.

Good luck!!
