Not owning all those components I'd just guess at the correct order, but:
1: OS3.9 + BB1-4
2: Mediator setup
3: Voodoo Picassa96 setup
4: BPPCfix (whatever that is?)
5: WarpOS
Somewhere in there you'll probably also want to throw in your network stack. Probably at the end, after you get your Mediator and NIC recognized.
