You will likely see more deer on spot and stalk which equates to more white a$$es running away from you. A ground blind is easy to set up and move. But, you will watch more undisturbed deer while using a treestand. Scent control is a must. I don't recommend an airtight bag as it may promote mold and mildew. After washing in scent free detergent, I hang my clothes outside for the season. I live in the country though, so there are no city smells to infiltrate the fabric.

Get out and hunt. Observe. Learn from your mistakes. And, don't just fling arrows at every animal that walks by. Take at least one or two practice arrows/broadheads and shoot while in the tree.

IMO, you are not going to learn to hunt on here or on the computer period. You'll find useful advice and tips, but most of your knowledge will come while in the field. Get out into nature. Find a local mentor.
