As far as driving, two of us were shorter and more fairway bound, and the two others (myself included) were a bit longer. So the two shorter guys drove and gave us a solid option, and we just tried to murder the ball. It worked out, we played our two drives (longer guys), probably north of 90% of the time.
Again, others here mentioned go worst to best, but we didn't really have that order laid out, so with driving we did what I said above. Approach shots, we just basically went randomly. I had a number of decent approaches, and a couple other guys did as well. Basically we always had an option. Someone was always inside 10 feet for the bird.
We had mulligans, but blew em all except for one! Three mulligans a piece. Twice we each used a mulligan on a short putt, probably 8 feet or so, and didn't make any attempts! I used my last mulligan on a tee, and it actually paid off. Four of us hit terrible drives on the longest par 5 on the course, I said I'm going to use a mulligan, and I fired off a good one. I had a solid three wood next which gave us 50 or so yards to the green. We ended up with a birdie on that one.
