Stanley made a good book on how to do a basement rough in.
I would also suggest that you sketch and post your plans here, and post how you plan to do it. You'll get a lot of great advice here. The stuff I got from some of the pros here was worth 10x any book.
Some rules of thumb i followed:
1/4" slope for all drains.
Vent each fixture.
Vent should go up thru attic.
