All good advice so far. I'd also recommend you perhaps invest in a ladder stand or perhaps a lock-on with added ladder for access. Climbers are also good, but good ones are a bit more expensive and the trees they are suited for are a bit limited.
Advice about scouting is all good as is that about being as scent-free as possible. The hint(s) about plastic bags or plastic bins to store your de-scented clothes are good as well. I normally will put some fallen leaves on the bottom or cedar boughs, if they are common in your area. Most important is them being scent-free to start though.
Best not to stop for bacon and eggs at the local diner in those hunting duds too, as you've just defeated your whole purpose. I even stay away from drinking coffee en-route to my hunting area. Do NOT stop and refuel & never wear your work boots to hunt, if possible. Keep boots just for the woods, if you can.
A small day pack is nice and if walking any distance to your stand, keep your outer layer in the pack, or tied to it, so you don't get all sweated up walking in. When at your spot, add the outer layers for warmth. Also, if possible, change to a clean, scent-free hat when in place. Go ahead and take a whiff of a favorite hat some time! A clean one helps while on stand.
When scouting for sign & stand location, keep the sun's position in mind. Sitting at daybreak looking at a rising sun, frankly sucks. So try to pick a couple sites in mind as well as the rising & setting sun's location.
