Hello again, bit of late reply!
Sorry if I didn't make it quite clear; I am a student living in Eastbourne but I'm going to the University of Bristol next month, so I won't be studying down this way. I just wanted some advice on Eastbourne ones for the time being just to get me started However, as of 24/08/2009 I have made 85 finds, so I don't think I really count as a beginner anymore (although I probably still have a lot to learn)! As both of you have suggested, I plan to do some of the walks, such as the Harvey and Ziggy's Red Route trail in Hellingly, as well as the Six Bells Circular. As for Lewes, I need to finish the Church series I make pretty good use of public transport, so I am fairly mobile.
In regards to 'Pete's Haven', there was definitely something wrong with it, and after emailing the owner, he has taken it offline.
