Good luck on your new job and life!
Are you trying to figure out whether you can get to the rink sessions in time before and after work? That is an interesting optimization problem. Too bad session times change.
Frogs on ice has spent a lot of time indexing neat resources. E.g.,
http://www.frogsonice.com/skateweb/clubs/us.shtml
As an example, arenamaps.com lists 34 Philadelphia area rinks.
Personally, I would visit a few club and freestyle sessions, and ask skaters for opinions. Of course, skaters tell you their coach and rink are best...
It's been a while since I was there, but Philadelphia has skinny roads and some bad traffic. A GPS wouldn't hurt. I don't know how to site your apartment and rink so you can get to work and the ice quickly in spite of traffic, since a GPS only gives good-traffic transit times. Some people commute by train - e.g., look at
www.septa.org SEPTA is clean, fast and safe, but they don't go everywhere.
I was only there during a competition, but Aston is a really nice looking place, with lots of ice surfaces. The rinks and pro shop at the University of Delaware are famous, but the rink schedule supports the competitive student population better than the outside community, last I checked.
OT, but Delaware has nice beaches.
http://www.delmarvakayak.net/ is a very active kayak club. Lots of nice places to hike around PA, like the Appalachian Trail. If you like plants, take a peek at Longwood Gardens. They have some nice social dance stuff too, e.g., very active Scottish dance groups. Many colleges and universities with the facilities and classes they offer.
Anyway, have fun!
