Welcome to the forum, you are correct, it's a great resource and will serve you well as a new Beek. To address your question concerning equipment, simply put, more is always better! :)
I started this past January, I built my own boxes and decided to go with all mediums, 8 frame equipment. My original plan was to have 2 to 3 hives this first year...as it stands now, I've got 9 hives and 2 Nucs. :laugh:
Not sure how many hives you want to start with, I strongly advise on "at least" two...lots of advantages to having multiple hives for a Beek.
You can figure 3 to 4 boxes for your brood nest, beyond that, depending what kind of year it is and how your girls do, you might stack anywhere from 1 to 4+ honey supers on top of that.
As you will quickly learn in Beekeeping, opinions vary GREATLY, you have to find what works for you. I personally like your all mediums and no chemical treatments approach...I respect the concept of foundationless but personally think you may want to gain some more experience before going in that direction...That and 50 cents will get you a cup of Coffee. :-D
