Long time brewer here in my past life.
3 tier full mash system, I've pushed 12% alcohol, up to 20 gallon batches, had NINE 5 gallon corny kegs at one time, with 3 different flavors on tap.
For the newbie brewer, don't worry about grain or patial mashes, and you don't need that much equipment, even bottles. I had ZERO issues even using 2 liter Coke plastic pop bottles. It's food grade plastic, the cap is reusable, and I honestly got darn tired of bottling 12-16-22oz bottles when I was brewing 12-15 gallons almost every weekend.
My local home brew store north of seattle that ships kits and ingredients, another fun part of brewing is growing your own hops, and these guys sell rooted hop starts in the spring/summertime.:
