I'm on a different game version (GOG), so the aobscans might fail. They are easy to find, though:

Infinite Health: float type, each red circle equals 2, and a half circle equals 1. So if you have 4 circles at start of new game, scan for 8. +4 offset and you get maximum health.
Infinite Mana: byte type, exact match for value on screen. +1 offset and you get maximum mana.
Edit Money: 4-byte type, exact match for value on screen. +4 offset and you get maximum money (99999).

For invincibility, do you mean invulnerability, meaning you don't take damage and also don't get pushed around or interrupted, completely ignoring enemy attacks? As for infinite jump, I haven't looked into it yet.
