Does a higher number mean a higher payout, or is it just a tracking thing, or what?
this is mostly a tracking mining-porn thing.. a higher number does not mean a higher payout.
Currently difficulty is about 12,000,000 ... if you get a number over that, you have actually solved a block. If you get a number under that, you still submit the share to the pool as proof you are doing work.. but the share doesn't actually create any new coins. In general, pools pay a fixed amount per share no matter if you actually solved a block or not.
I think you are asking... Is it possible to submit the same share to multiple pools, and thus get paid multipled times for the same work... short answer: NO. Long answer: Each pool includes a unique string when they send you a work request. If you send a share to a pool that did not originate the work, it will know, and reject it.

Thanks!
That answered everything. At least till the next time I run into a wall
