On the totes for your gear, I use 2 of the large clear totes from Walmart. One for clothes and the other for gear, being able to see what's in the totes and where really helps. You can grab a thin roll of weather stripping that fits the groove in the lid of the clothes tote, it won't be 100% air tight but helps keep contaminating odors out.
A good backpack truly helps but doesn't have to be expensive, Academy usually has some decent ones. Look for one that has several outside pockets for small items and straps for securing extra clothes. Make sure the pack you pick out has a waist belt, most have small pouches attached for small items. The waist belt will make a HUGE difference when carrying heavier loads, it takes most the weight off your shoulders.
Head lamp as mentioned but also a small handheld light, I use both walking in as the handheld throws light farther for distance and you have a backup light.
6' of surveyors tape to mark the end of a blood trail that you will have to take back up the following morning. PLEASE REMOVE any surveying ribbon when you're done with it, you'll figure out why I say this once you start scouting. Use small pieces of toilet paper on a hard to follow blood trail, this will give you a good line of travel when looking for that next drop of blood, plus the rain will dissolve it later so no need to remove like ribbon.
Reflective tacks called Bright Eyes for marking your trail to a spot you want to hunt in the future. If you use an app like Onx then you'll only need to use the tacks to mark certain challenging sections of your path.
Kill kit for gutting.
Some sort of adjustable webbing strap for dragging deer out. I like one long enough to wear across my chest and one shoulder, then grab it behind you with one hand and use your body weight to help pull.
Dried milk weed! You will learn more about wind currents from watching this stuff float around in the wind than any manmade product. I don't go hunting without it anymore. Plenty of youtube vids on it.
A good emergency kit. You just never know.
Tree umbrella. Keep it in your gear tote unless a chance of rain, then throw it in you pack.
Note.....ounces add up to pounds and doesn't take much to make a pack heavy. Heavy packs suck and we've all been there. Do your research and don't blow your funds on unnecessary junk.
