Yes, all of the Flyers' on-ice sessions at Camp are open to the public.
In-season practices are all open to the public except during playoff time when the coaching staff may want to have some private practices.
The Camp schedule and player roster is usually announced about a week before the start date. We all will be watching the Flyers web site for that announcement in early September:

The Camp Guide is a great thing to have. It includes extensive info on all the players and includes pictures. It can be downloaded and printed from the Flyers web site announcement. Also, if you can make contact with the right people at Camp, you may be able to get the actual color Camp Guide.
If I'm reading between the lines of your post correctly, yes, you can talk with the players and get autographs in the front parking lot as they arrive, and as they depart, "to and from" their east side secured parking area.
