hi, this is probably a little late and you may know about this already but the eastcoast has a pretty good site dedicated to surfing there
www.eastcoastsurf.co.uk
they have a forum also with a bunch of really nice friendly people on it, so maybe you could post your question there.
as to places i am assuming Cromer is one of the biggest places to surf on the east coast since they have a cam setup there.
hope that helps
Jonathan
