1. Enchanting table access, as well as exp before the tournament starts. You also get credits towards the walls server when it launches, and a chat prefix. If you really donated that much I would give you the highest donor class status (where applicable) on future servers (this summer, I will definitely be launching a Walls server, and probably a Super Smash Bros and Capture the Flag).
2. Probably this weekend. Before I implement that, I will completely disable crafting, prevent players from accessing the chests before the tournament starts, and some decent working anti-fly protection.
3. Not exactly sure what you mean on this one, please explain.
