I am sorry to throw more confusion at you, but I totally disagree with adding dead rock and hoping it seeds well over time. From my experience one of the greatest joys of building a tank is discovering all the amazing things that pop out of live rock.
I go so far as trading live rock for live rock with my LFS, in the hope of hitchhikers. I would also add a variety of different live rock over time from different sources if you LFS's around you.
If I started over, I wouldn't add fish 6 months, just because I loved watching the explosion of life in my tank from the live rock I added.
This of course is all just my opinion and admittedly from a live rock addict.
