There are as many different designs for aquascaping as you can think of. Personally, I think whatever looks good to you as you move the rocks around and stack/combine them, is what you should do, although there are diagrams of scaping out there.
10 lbs of live rock seems way too low for a 44 gallon to me...most use anywhere from 1 to 2 lbs per gallon.
