If you really would like to learn something, I would sign up for a walk on trip with Skipper9 or one of the other great captians on this site.

It is invaluable the things you will learn from them in one morning.

With that said, the fish are in transition right at the moment. Post spawn walleye can be difficult to target with any particular method. You must try everything until you get a program set up they will take.
We have started to troll spoons, crankbaits, or crawler harnesses on the days with no wind and drift bottom bouncers on normal days. Some are casting weapons (mayfly rigs), but I have not heard of great success yet with casting yet.

If you read through some of the reports here, you will see where, what and how updated on a daily basis.
