I've camped there a few times during October. The fishing is usually pretty good. A lot of bluefish around, mostly smaller. The chance at some huge red drum and stripers is definitely there too.
For the big fish, you definitely need surf gear. 10'-12' rod with large reel. The local bait shops usually have economy setups for $30. Probably not the best, but give you a much better chance at landing a fish (and not breaking your expensive musky rods, casting 4-6 oz. weights). For these guys, cut bait, usually bunker, spot, or just about any fish (usually head or whole smaller fish) on a hi/lo rig or fishfinder rig. Fishfinder is usually the way to go for large baits and getting them out far. Mullet rigs work well in the Fall, if the small blues aren't around. There should be a bunch of mullet in the surf when you go, and likely the top producing bait for just catching fish. Although, the small blues have a habit of constantly stripping the bait away.
For the blues, bluefish rigs work great on fish from 12"+. These are double rigs with floats and either steel leader or heavy mono. Tip these with finger mullet fillets or chunks. If you are only getting fish up to 12", or having a hard time setting the hook, then down size on the hooks (fresh water "bass size" hooks work, but will rust if you don't rinse them after using.) Hold your rod and set the hook at the first nip.
Get yourself an Atom popper lure. This is a blue surf popping lure, which works great with mullet in the surf. You might run into some sand eels in the surf (more in NJ than MD). If so, then small plastic eels work pretty well.
#1 thing that you want are some sand spikes. These can easily be made from PVC if you don't have any. 3' ones are nice size for transport and use. 4' will get you higher but a bit harder to carry. These are nothing more than rod holders, but nothing will mess your reel up more than sand, or rinsing sand off with salt water... I usually do a large fish rod (with baitrunner reel), then a lure chucker / small fish rod, depending on the fishing.
The striper "run" likely won't hit there by then, but if it does, clams work great. This seems to be something more used from NJ north, but they still eat them in MD. There are a lot of clam beds in the area, so are still natural food. Mentioned above are the sand fleas. Sometimes the best bait around. Don't cast these too far out. They also work in the inlets at times, without any weight, cast into the current seams.
In the inlet, fish the current seams. Swim shad seem to be the best around there. Although I have caught fish on plastic jerk baits, large Bomber lures (work in the surf too) and bucktails.
Here is a great site for info.

We had to chase a tent, full of clothes, sleeping bags, and other stuff, about 100 yards... Dig some holes and burry a piece of fire wood with your tie downs tied around. This is pretty easy in the sand there.
Have a great time, this is one of the best times of the year there. The water is still swimable, if you get a few days in the 70s-80s. Even if not, you can still likely wet wade, although waders are a good idea to pack. Boot foot ones seem to work better, since the stocking foots will fill up with sand.
