In reply to alecjcook: Hi Alec,
The obvious crag for you, as others have said, is Wild Cat. Willersley is more polished and the routes are more committing and High Tor is for later!
For a start, I would tackle some single pitch routes while you get used to the rock. There are some reasonable easier lines on Slippery Slabs (they're not very). Pink Panther is quite reasonable for the grade as is S.S. Direct. On the main crag Cat Walk & Pupilla (not much harder than Cat Walk and easier to protect) would be good for starters. Lynx has been mentioned, and it's good, but personally I think Lobo (which shares top pitch with Lynx) is no harder and easier to protect at the start. For a biggish two-pitch route I'd recommend Jackdaw Grooves.
If you have transport,it isn't far to Ravensdale. There is a number of steady routes with some good single pitch routes near the cave. Tria is a superb HS and a good first limestone lead for a competent leader. Then there are some great multipitch routes on the main crag (though Medusa is very polished, sadly).
Go steady and, although there's not too much loose rock, test each hold. There are some great routes for you to enjoy on these crags.
