The guy to answer the Ned questions is Dtrs5kprs (Dave). I think if you shoot him a PM, he'll provide a ton of info, or some links to the info.
I can tell you the types of areas I target in the winter with the Ned, basically I have a milk run of a half dozen spots, I learned those locations through time on the water, and usually they hold bass in the winter, several of them are points at cove mouths that have timber out in 10-30 FOW, usually they are also rocky, not mud bottoms, main lake 45 degree chunk rock banks, bluffs can be good, if you can find a shelf coming off a bluff that is in 20 FOW and has some timber, that can be worth fishing.
Winter Ned bites are going to be light, especially when you're fishing deep, usually your rod will just slowly load up, feels almost like you're pulling through moss, but they'll hang on to a Ned pretty well, so if it takes a second to recognize what's going on, you can still usually get them.
It wouldn't hurt, being that you're new to bass fishing, to go out with one of the guides like Bill Babler or Pete Wenners. Winter fishing a big lake like Table Rock is a pretty daunting task even for experienced fishermen.
