Going salt water fishing for the first time - tips?

Ok, I'm almost embarassed to admit this: I'm an avid fisherman
(bass/catfish/panfish), but despite living only 6 miles from the
coastline (South Carolina; about 90 miles south of Myrtle Beach), I've
never gone sal****er fishing. All I've ever done is freshwater.

That being said, my brother and I have decided to go this coming
weekend to give it a try. We'll be fishing small streams and jetties;
nothing too deep or far out as we'll just be in a 14' jon boat.

From my reading, I'm thinking that our most likely catches will be
sheepshead, maybe some drum. To tell the truth I'm not really
concerned with any particular type. Basically, I just want to get a
good recommendation on gear setup and bait to use (for whatever might
be caught in these areas during this time of year). I've got some
larger reels/rods that I use catfishing, and I've also got a few other
bass combos that I use. I normally spool the catfish rods with 30lb
test line and the bass setups with 12lb test. Any advice as to how to
set these up for sal****er?

Thanks for any help offered. I'm hoping to get a little more
experienced with this and hopefully make a hobby out of it. For the
moment I know next to nothing though .
