Sinkers and Swivels
A good thing to remember is the smaller the sinker usually the better you are. The sinker is to get your line down to the bottom. Too much sinker gets you down to the bottom but makes you fight the sinker instead of the fish. When the fish is not at the bottom but running somewhere in the middle a sinker will hold live bait down to keep them where the fish are.
Swivels are a must do. Swivels keep your line from getting all twisted up. Allows you a better feel for the fish and keeps the line from getting kinks and knots as your bait swims around.
