Read what the rest of the posts say, lots of good stuff. The one about walking to and climbing in light clothing and then putting on the heavy stuff when in the tree is a good one.
Something not mentioned, and forgive me if I missed this but it appears you have not bought a stand yet, is what to chose for a stand.
I'll not champion a spicific brand. I've owned a good number over the last 30 years and with the exception of my first one, a Baker, all of them have had plusses and minuses. That old Baker though.................well it tried to kill me a few times.
Here are some general things I would look for:
1. Folding stand. Makes it much easier to get to and from site. Takes a little longer to set up though. And I will admit that I have two Timbertall Baby Lites that do not fold but rather nestle that I really like but in general stands that fold flat are better for carrying.
2. Pick as light a stand as will do the job. The less the stand weighs the further you are likely to carry it. This makes you less likely to pick a spot because it looks "good enouogh" and is close.
3. Ask about how easy the stand is to attach to the tree. I like my climbers but have used strap on styles a lot. Strap ons can be a pain. But, and this is important, with a strap on you can almost ALWAYS find a tree very close to the spot you want to hunt. This is not always the case with a climber. Some of the areas we hunt are heavy on the Live Oaks and they just do not lend themselves to climbing, especially the older trees.
4. Make 100% sure you have a GOOD carry strap system. Pads on the shoulders and a strap around the waist just as you would with a backpack to transfer the weight to your hips. Same reason as for a light stand.........you will carry it further.
Last thing...............with a light, easy to set up and easy to carry stand you will be far more likely to change spots because it will be easy. I don't care how careful you are with scent and the like it is a good idea to move from spot to spot and if your stand is a pain to move you will not so it as often.
