Is it really that hard to post human-readable summaries (at least year/model) for each link?

You should also check out the local bike shop (LBS) scene in SC, and find a trustworthy one or two (or maybe a co-op) that will help you out with advice & repairs. Return the favor by buying at least the common low-end supplies there (tubes, screws, lube, etc). An experienced pair of eyes giving your bike a once-over is a great safety/performance check.
