I suggest keeping it simple for your first purchace.
Buy at the resort you want most, and buy enough points for how often you'll be going.
The smallest room you'll be able to book with all 6 people is a 2 BR. There are no 1BRs that have occupancy for more than 5 people. So look at the points calculators for weeks that you're likely to travel and check out the points ranges for 2BRs, as they can really vary, even at the same resort. For example, a week in July at AKV is 241 points for a standard view 2BR, but 311 points for a savannah view 2BR.
