Standard high low rig is the way to go for porgies. Depending on where the fish are and how they are biting, you can adjust the rig easily. Sometimes they're close to the bottom and you can go with a low-low rig. Sometimes they're above the piece and you need a higher hook.
For porgies I like the 1/0 gami octopus hook. Beak/baitholder hooks are nice too. Don't want to go with too small of a hook though as you want to weed through the smaller and still have a good hook that can handle seabass or even a blackfish. I usually buy a pack or two of the presnelled gold bait-holder style porgy hooks with a red or orange bead on them in the lagest size I can find.
Unless the current is really running and spinning the baits, I use no swivels or snaps. Surgeon's loop at end of leader to make a loop to slide sinker onto. Couple inches above gets an in-line dropper loop and another about 18" above that. Two simple knots everyone should know.
On the droppers you can slip on pre-snelled hooks you pruchase or tie yourself. They just go on loop-to-loop style.
If using presnelled hooks, you can take one and tie a dropper in the middle of it and add another presnelled hook. This can go right on to your main line/leader droppers creating two hooks at the bottom or top.
For porgies keep your baits on the small/medium size with not too much hanging off the hook. Too much hanging clam or worm and they'll rip it off. Personally prefer clam baits as worms seem to catch more but usually smaller. There are times that worms do shine and will be the only bait they seem to want though.
Usually the porgies are around structure. Jetties, wrecks, reefs, mussel beds, piers, etc. I've caught them off local piers and even sabiki'd them up around docks, though generally they are smaller than regulation size.
