Sorry to hear about your crash; I hope the pain goes away soon.

One thing that might help with ride skills is to find a good group to ride with, people you can trust and who are willing to help (your ride leader sound like a perfect such person). Do you ever ride with some of the Philly clubs (I'm thinking BCP or SturdyGirl)? They have always been very nice, and I've learned a lot from the people on these rides.
