The first thing I would do is read the owners manual from front to back then back to front and do it at least a couple of times. If you can do that and reconize the terms used with ease you have come a long ways.

Next I would start by shooting and cleaning as purposed in your manual and get comfortable with that. Next step would be branching out and trying other projectiles and powder as you feel more comefortable with your gun.

These two steps should mean shooting at least 100 rounds at the range before heading into the woods.

Tools and other supplies should be listed in your manual other supplies will come on a as needed basis. (hope you live close to a gun shop).

If you don't have a manual for your gun get one I would not attempt to shoot it without one.
