There's the trick to figuring out how many people will fit in a tent. Usually, the number is about right, but with conditions. First, it allows no room for gear in the tent. Second, it assumes that everyone is about 5'8" and 160 pounds. If you want to stash gear in your tent or if you will have larger people, start subtracting from the number of people who will "theoretically" fit.
I would gladly suggest a few good brands/models for you, but I need to know roughly how many people you want to be able to fit in your tent. As a general rule for a fair weather non-backpacker, the Kelty tents at Costco are hard to beat for price and quality.
I'd be a better listener if you stopped talking about stupid crap that doesn't matter.
