The only rig I use for bait is a three way swivel with about 7 inches of 15-25lb leader coming off the middle ring of the swivel, and a size 1/0 silver Mustad Circle/Egg hook (pack of 50 for like $5 at Wholesale), the leader coming from the bottom eye of the swivel should be anywhere from 20 inches to 6ft (I'll get to this), your weight should always be a pyramid weight and I like to use a 3oz this time of year if you plan on not walking far out on the jetty. You will thank yourself if you pick up a couple tubes of rubbery magic thread, the thread stuff works, but the clear rubber stuff can be purchased in a clear dispenser and is hassle free, if it locks up, just shake it up and down, Shrimp only last about 2-3 bites max most of the time, the thread helps it last until you catch a fish or two, fold the shrimp in half and wrap it down a few times, then just wrap it head/tail down on the back of your hook (I probably go a bit overboard on wrap, lol), check out my thread in the Saltwater Fishing section 'How to make a Shrimp Pump' it will pay for itself the first couple uses.
Your leader depends on how you fish, you will want to fish really close to the jetty, so a short weight leader is your best bet, your bait must stay off the bottom, Crabs will make short work of it, you want your hook a foot off the bottom, and think about the angle of your line once casted, your rig won't be standing straight up unless your standing off the finger jetties. Longer leaders are for surf casting long distances, or casting far off the jetty. If you are wanting nice size Lings and Cabezon, I'd use heaver leader than what I recommended, lol.
Bass gear and methods work also, like soft plastics (Swimbaits, Grubs, Worms, and Crayfish), and the jigs I posted a pic of in Troutier Bassier's thread.
