Probably in late March or early May so that they are ready when the hummingbirds return. You might not want to fill them up all the way the first time so that you don't waste as much sugar. After that you can fill the up all the but just remember to change to nectar once a week.
In Minnesota, hummingbirds may come out as early as February-March. However, if you have a hummingbird feeder, the chances of them showing up will greatly increase.
There are also shrubs to plant that attract hummingbirds, such as Red Buckeye, Cape Honeysuckle, and Butterfly Bush (Buddleia).
Absolutely! Ruby-throated hummingbirds love it here. They arrive in May usually & stay for the summer.

Yes, woodpeckers drink from hummingbird feeders. Red-bellied woodpeckers even pulled the plastic flowers off the feeding holes of my hummingbird feeder in order to get better access. I have also seen downy woodpeckers use hummingbird feeders.
Sugar water. They like red feeders. Google hummingbird+feeder for more.
It depends on where you live. Hummingbirds are flower feeders and consequently tend to migrate when flowers will be in bloom. So feeders should be put out in spring when flowers start blooming and should be kept out until the first frost. Its also important to change the liquid in feeders every week since it will begin to ferment.
That is normal behavior for a hummingbird. You can try making several different hummingbird feeders available so they don't have to share the same one.
They will feed when they return return from their migration. They will return in the spring as soon as the flowers bloom. Putting out a sugar water feeder should help attract them when they return.
