Hey,
Me and MrEniro made a clone of this forum some time ago, we got a little further than you but never totally finished it. If I were you id move away from the old idea of making a huge admin control panel, there is no real need for them other than for extra crazy tools like in phpBB with such features as mass-email and auto-prune set-ups.
I'd be tempted to go more in the direction of inline administration, and perhaps any extra features you want admins to have could be thrown in the user control panel. That way you dramatically reduce your coding time, and save admins a crapload of time having to find things in the panel.
When creating the user system you may want to consider something that a few of us said we would start, but never bothered with. If you create an abstract layer for gathering user data, you could in theory use ANY user system. This would be code people would die for, and is the biggest problem we face in sharing pre-made code. Imagine being able to use FreakAuth or any custom system just as easily? If you like the sound of this let me know, im happy to help but im not doing all the code myself :p
