In reply to mtnash:
One of the best ways is to just watch people on a route you've done, see how they tackle the bits you struggled with, but beware of picking up bad habits - just cos' everyone you watch does it doesn't necessarily mean it's the best approach for you (especially if you are shorter or taller). Retry the route trying the technique you've seen.
Videoing yourself climbing and watching it back can help you work on particular techniques - it's sometimes easier to see what you are doing wrong from a distance.
Also, talk to people, generally we are a pretty friendly bunch and will happily give a pointer if someone is "stuck" but you probably won't get a pointer without asking (as unwanted advice can be annoying)
Oh and I know you want to be climbing amazing things straight away, but do take care to warm up & down every session, and don't push yourself too much too early its very easy to twang a pulley tendon early on before you've built up strength in your hands and arms.
And remember FEET
