Most of the little shore diving I've done has been at Tulamben, in Bali. Entries and exits are usually not a big problem there, but on a couple of occasions the waves have been big enough to make things difficult. The fact that the "beach" is made up of large rocks has been a concern.
One approach is to have a buddy carry your fins into the surf so that you can concentrate on keeping the camera safe. (If you're both carrying cameras, one diver can still carry both sets of fins and wait beyond the surf line, and the other can bring the cameras out one at a time.)
As mentioned by Marc and the redoubtable "Scuba_Kiwi", if you're shooting wide-angle with long strobe arms, having a reliable arrangement to keep the arms under control for the walk to the dive site and the entry is very important. I use a system of three fastex clips that makes the entire housing and arms into a rigid triangle.
I also have two "suicide clips" attached near the middle joint on each strobe arm. Either (or preferably both) can be clipped on to D-rings on the chest straps of my harness, allowing me to have both hands free to put on or take off fins etc.,
Having both hands free is also vitally important if you want to release a delayed SMB (submersible marker buoy) - or need to render assistance to another diver either on the surface or underwater.
Incidentally, I personally consider handling an SMB to be a fundamental skill, which unfortunately is not part of the standard PADI course curricula. If this is something you're interested in knowing more about, here is the link to an article I wrote a couple of years ago for Asian Diver:

One final matter worth thinking is arranging to keep your housing damp until you can get it to rinse tank. A small towel folded up inside a pocket (or hidden on the beach near entry/exit point), soaked in sea water, can help keep the housing and its seals from drying out while you're walking back to your car or whatever. Keeping a large bottle or two of fresh water in the car (in addition to what you need to drink after a dive) to rinse off the housing might also be worthwhile.
