Hi alphanikonrex, and welcome to APUG. It's a great place to come with questions, so ask away. Don't worry about seeming stupid- everybody has been there. You'll get conflicting opinions here and there but you will get answers.
You don't say where you're located, but there may be a way for you to find a group darkroom or a mentor if you're near a metropolitan area. I don't know about you, but watching somebody do something cuts my learning time in half over reading about it. Check your area for workshops and groups that share darkroom space. You might also look around for photo shows and used equipment sales. Lots of good darkrooms are being broken up and sold off. It's a good way to pick up the basics without spending too much money.
The 16oz tank is not really a mistake, just a choice. You may want to buy two reels and use that tank by putting an empty reel in on top of your full reel. It may save you having to buy one later when you get used to the process and want to do more than one roll at a time. I haven't used stop bath in years - water will stop the action of the developer and it's one less chemical you have to buy. If you really think it's necessary, go for it, but many of us just use a water bath between developer and fixer. I would also question the need for hardener in your fix. There is another thread on here now about that issue, but suffice it to say that many of us also feel that it is unnecessary - and actually causes much more water use in washing out the fixer. Go with the basics- develop, wash, fix, wash, wash, wash. If you want, add a fixer remover between the first post fix wash and the second, it cuts the washing time.
Good luck, and welcome to the club.
