Hey Adam.
At the venue I judge at, we typically start at 7:30, and everyone is always interested in drafting, so that's pretty much all we do. For drafts, the store owner and TO sells packs for $3 a pack.
From my understanding, a booster box, which contains 36 packs, is intended to fully supply an 8 man draft. After the initial 3 packs / player, this leaves 12 packs remaining for prize support, matching your 1.5 pack / player setting. So in terms of that, I think you're running events very fairly, but for $15, I wouldn't do less than 1.5 packs / player.
For the number of rounds played, we cap it at 3, and distribute prizes based on record instead of rating, and my players generally prefer it as they don't need to worry so much about tie breakers. I might consider holding a vote amongst your players and see if they would prefer a different method then to go until a clear winner is established.
As far as table numbers and match slips go, I judge at a venue where we get ~ 20 players, and most people know each other by name. People will generally crowd around the parings once it's printed, and go find each other with limited intervention on my behalf, so it's not much I need to worry about… but my advice to you is to use whatever you find works best, and I think slips + table numbers to be a perfectly fine way of doing things.
