I'm with @
friendofpugs. Your best bet is to list a few bikes on the C&V appraisal forum and ask for advice as to whether those bikes are worth the asking price on craigslist. If you list your city and height, people will tell you which bikes will fit and they'll scour the ads for you. Nothing like free labor, right?
In terms of working on bikes, that's easy and they're are a ton of really good youtube videos on this.
Also what are you planning on doing with your bike? A commuter or all around bike is different than a racer and some of the bikes you've listed are really racing bikes.
