I have heard plenty horror stories here about PHL and being pathetic on upgrades, cleanliness, and waits, but being the first time I want to know what to expect.

I am coming in 5pm on Friday and leaving at 9am on Sunday....is PHL done by shuttle bus, what is approx wait times for pickup from airport, and back to the airport if so?

Upgrades, I rented a full and basically expecting nothing. Not an issue I guess.
