In a book, I read that to have stable biological filtration in a saltwater tank, you need to fill atleast 1/3 of the tank with live rock. Do I still need this much live rock if I use live sand?

Not sure where they get 1/3 from. The suggested LR amount is 1.5 to 2 pounds per gallon. IMO, live sand has no impact on this recommendation.

That sounds like a good amount. When you go get it, look for the lighter, more pourous rocks. They have mor room for things to live in/grow in.
And, you may eventually want more. I told myself when I got my 10G, I was going to get 10lbs of rock. I came home with 24lbs!
