Notsorichguy has summed it up nicely.
I reloaded for decades before getting a tumbler and am still getting used to having shiny brass. Until I got it, I used the sleeve off an old flannel shirt. Dumped the dirty brass in, soaked it in lighter fluid, grabbed both ends and shook! Clean in a few minutes - clean enough to reload without issues. (I also tried throwing the brass in with the laundry. It worked but Memsahib objected to her frillies getting torn and drying the stuff was a nuisance.)
Maynard's suggestion about a caliper is good. It's particularly important if you're using high-end loads or trying for match accuracy.
If you trim your cases, you will indeed need that deburring tool.
WRT lube, I'd tried a bunch of types to use with the pad, but they were all - to me - a flaming PITA. Somebody showed me Imperial Die Wax and I've used it ever since. It's like a small shoe polish can. Lightly touch your finger on the wax and roll the case between your fingers. Very little mess and no stuck cases.
Speaking of stuck cases, you will at some time need a stuck case remover. You will not need it until it's the evening before you leave for the big hunt; the store will be closed. So drop $6 now. Surprisingly cheap and, when the moment arrives, a Must Have.
A hammer bullet puller is worth having and they're pretty inexpensive. The trick is not to pound like you're driving 6" spikes. Swing fast, but let momentum do the work - ease up on the force before it hits the floor or table. Otherwise, they tend to break. (Ask me how I learned that last.)
I would get more than one reloading tray. They too are cheap and the extras come in handy.
Also - good lighting. No, that's not right. Good Lighting! Still not right... GOOD LIGHTING! Do a visual check inside each case after you've put the propellant in - double charges or no charges will show up instantly. Best bit of advice I was ever given.
Best of luck.
