Welcome to the site!
I would highly recommend reading the fishing reports and read them well!
Look up Steve Dezurik on the site and he will give you the information on the Jimmy D bugs. (Which I will give a personal thumbs up to for both smallies and walleyes! )
For an initial journey to the river for some walleye action, I would highly recommend going down to Evert’s Resort. Connect with Dean (the manager) down there and he will take care of you, giving you latest techniques and locations for the river. Right now, for numbers plus good quality, Pool 4 (redwing) is just about impossible to beat for the angler looking to get away for the day.
If that is too far of a journey, go to the Prescott bridge. You can launch in Hastings and head down river just a mile or two. This is where the St. Croix comes into the Mississippi river. A jig and a minnow searching around will find you some fish. If you have the time, I would get some super-doos and paddle tails and work those in the same area to get better fish (personal opinion)
If that is still too far, search around the Mississippi river forum for walleyes. There is good talk right now about Pool 2 performing well. However, Pool 2 can also be quite humbling to the inital maiden voyage. Heck, even after a few trips it can still humble a guy quite quickly.
Good luck!!!!
