Ava, while scent is a very important part of deer hunting it's a little different here in Pa come rifle season. Of course in archery season while the deer are still traveling natural travel routes and not being pressured scent is of the utmost importance. You'll find however that come rifle season in Pa the deer are being pushed all over the place by the pumpkin brigade (all of the hunters wearing orange). It's not that the deer don't care about scent as much but rather that they are primarily concerned with constantly moving as hunters push them. I typically just shower the night before, get up the next day and put on my clothes. All I do is keep my clothes in a duffel bag and make sure I don't wash them in detergent.
As far as what to remember I would say your top gear priorities should be good boots (don't go cheap on these, you'll regret it), a drag rope, a knife, flashlight and hot seat. If you get cold easy you'll be glad you have one of these.
