I've run yahoo leagues (football and hockey) for awhile now, so I'm pretty familiar with how they are run. I can volunteer to start one, unless someone else wants too.

I prefer these settings:

Goalies: 2
Centers: 2
Left Wings: 2
Right Wings: 2
Defensemen: 4
Utility: 1 (this can be a forward or defenseman)
Bench: 3 (this could be goalies or skaters. You rotate them in and out of your active lineup as desired)

A typical league would have stat categories like:

Goals
Assists
plus-minus (combined for everyone on your team)
Penalty minutes (yes, more is better)
Shots on goal
Special-teams points (PP + SH. Some people like to split up PP and SH points and have them as separate categories)

and for goalies you'd have:

Wins (or points, 2 points for a win, 1 for a tie)
Save %
GAA
Shutouts (optionally)
