If your LSB is a Trek dealer and the computer you are looking at is a Bontrager, let them install it. My wife got one for her bike for me to install and the instruction totally suck. The computer may be a good one; she's only had it for two weeks, so I can't make a definite statement. However, if someone didn't explain or mention wheel size setting's you would never know about it because it is only mentioned once but doesn't tell you how or where to set it. That holds true for the other functions as well. The instructions are nothing but a single piece of paper printed on both sides with 80% instructions in a foreign language. The other stuff you mentioned is child's play, even if you aren't mechanically inclined.
