In reply to snookyb:
It's best to have a bouldering mat for the cutting boulderfield as the landings are rocky. You may also find the problems a bit powerful for the grade since they are quite short problems.
There is the neddyfields bouldering which is more technical climbing with grassier landings. I would probably suggest climbing here first of all. All the problems are on the same edge so the more experienced can guide the less experienced and be more social etc
For DWS look at Cave Hole, temporary lifestyle is a very good intro. and a little further along towards the lighthouse is the red crane traverse (and other fun problems). None too high, easy to get to and great fun. As for the salt water just wash your shoes in clean water at the end of the trip?
have fun.
