Pike will eat live or dead minnows. Depending on the day and body of water, dead minnows may be the only way to go. I had a great spot I used to fish. I would use live suckers, and live shiners. Some days the suckers would really out produce shiners, other days shiners were the way to go. Most days it was about equal.
As far as where to fish, start with a good pike lake. As has been said, bays, or points are good. Any place that funnels fish is also worth a look. Depending how many tipups you can use, vary the depth of water fished, and the depth you set the tipup. I have caught fish setting the minnow just under the ice, all the way to just off of the bottom. I have also caught lots of pike in very shallow water, and deeper water too. Don't be afraid to move your tip ups too. If your spread is not producing, try moving to a different hole. Sometimes a small move can make a huge difference.
Hope this helps.
