Everything Deb said is correct. Once you get the side stuff off, you'll need a flashlight to see where that allen hole is way deep in there, and figure out the right size allen wrench.

An exacto knife works for trimming the tape. If you tape the bars STARTING from the bar ends it will hold itself down. I actually put a little dab or two of epoxy at the very ends of the tape on itself after trimming the tape, as your hand does a lot of rubbing there while shifting and it will hold better over time.
