Start with the
10 Essentials and go from there.
As for getting outdoors, I'm sure Michigan has plenty of great opportunities to get outside. Start with a day hike in nearby park. Plan for an hour or two of walking. Bring a camera, maybe a book on birds, trees, bugs, or whatever you find interesting. If you like the day hike experience, find another park with an interesting feature. Drive there and take a walk.
If that's to your liking, try an over nighter. Car camping is an easy start. Drive to a modern campground with showers, flush toilets, and any and all gear you can pack in your car, near an interesting place to hike. Eventually, you may find that you need the back country experience to find what your looking for. That's when the lightweight, technical gear comes into it's own, especially in the rain and snow.
As far as buying gear, start out easy on the money, but what holds true for guns is doubly so in camping, you get what you pay for; buy once, and cry once. You'll buy stuff that you think fits the bill until you get out there and use it. Sometimes you just have to use a piece of gear in the field, in order to understand it's limitations.
The most important part about camping and hiking, just get out there and enjoy.
