Without breaking the bank, I'd start with a couple Swedish pimples and cast masters in silver and gold. A larger size of each for walleye, and a smaller size for perch. You might want to pick up a couple smaller ice jigs for perch as well. If you have the cash pick up a swim bait or two for walleye, if not get them next season. You don't have to spend a ton of money, work your way into it over time.
