We're going to make a trip to Safe Harbor for the first time this weekend. Any recommendations, cautions, or resources for a group wanting to get back into sport climbing on some easy routes (preferably 5.7-5.9)? Any equipment needs we might not expect?

Does anyone know of a good guide book for the area? I found a couple pdfs, but didn't see a book recommended. 

I realize this is short notice, but I only just now found this group. Thanks!
