Here is what I would do in your situation
1. Set up the ground blind as you will give it at least 2 weeks before you try to hunt the stand to let the deer get used to it. I set a blind in the morning and hunted it in the evening and the deer where very jumpy around it. Two weeks later they didnt even know it was there.
2. When you get home wash your clothes it will be fine.
3. I wouldnt bother with setting up an attractant or salt lick because you are using an intersection of 4 game trails. They will use them the only thing you have to worry about is being there when the deer get there. At this point the lowest impact set up is key you dont want to mess up the area with something new.
4. Scent drags. Im not the one to really talk about using them because I have tried them in the past with limited success and just dont bother using them because if Im in the right spot I wont need to mess with that stuff. Early in the season I wouldnt worry about putting scent out. However when the rut starts getting going late oct into november if you wanted some doe estrus couldnt hurt.
