Wow! You will be busy fishing for all of the species. Check Airplane Island for smallmouth and pike.
Walleye are med light spinning reels, jig tipped with minnow. Some folks say color matter, some don't. I liked the yellow with red eyes, but really don't think color matters. A good depth finder to mark them matters. A good walleye chop on the water is helpful. There are two islands on the way to Brule Narrows that are usually good with some humps nearby. Just run your depth finder out from the islands until you see humps or dips with fish stacked on them. Cast out and reel to the area the fish are stacked. I am not a fan of the walleye fight, but love to eat them.
Smallmouth are the best fighters. The bigger ones will be deep, but we used jointed Rapalas on a med light spinning reel for them too. We would cast to the bank and let the bait set until the splash went calm. Twitch it and hope for a top water hit. If that didn't work then strike the rod down and reel in at a steady rate. Sometimes they would hit close to the boat. I liked the islands around Mermaid Rock, but they are on the Canadian side. Mepps spinners worked well too.
Crappie are sweet. Red Gut Bay on the Canada side was my favorite place on Rainy for crappie. Smaller jigs tipped with minnows were the way to go. If you stop by the Holiday Gas Station (used to be Rainy Lake One Stop) and ask for Dave he is an awesome fisherman and might help you out. Tell him the old Holiday manager, Carpenter, recommended him. The Rainy Lake Sportfishing Club puts crappie cribs out every year on the USA side. I would find a map of them if I wanting to catch crappie.
Pike are easy. I think you can throw a coat hanger in the water and they will attack it. Any little cove with trees, rocks or weeds will work. They are icky slimy fish that ruin lures and have red meat. Fun to catch though. We hated them when I lived there.
Musky fishing is tough. You cast a hundred times with big buzz baits or buck bait spinners hoping for one bite. Not my favorite fishing.
ShaSha resort has some good burgers and a ton of chipmunks. Thunderbird Lodge had the best steak I have ever eaten in my whole life. I am not sure of she still works there, but the kitchen manager found a hair on a plate and had every dish washed again one time.
