Some good examples to start from can be found in the Intel pubs.

		80386 System Software Writers Guide
		80386 Programmers Reference Manual

They give  flat, segmented and hybrid (demand paged) examples.
The manuals tend to be a bit pricey ($25 each) for their size, but 
worth it. I too am working on a project using protected mode, but not
as ambitious as your talking about. Do you plan to return to DOS or is
this strictly a protected mode application ?
