Another resource is njbikemap.com Although focused on NJ, it covers eastern PA areas around Philly, Bucks County, etc. Probably best bike specific map in the country. Look closely and you'll find all of the bike trail, dirt roads and other useful information for putting together a great ride. Lists places of interest and identifies all hills with total elevation gain (little green flag indicates top of hill).
