Setting up new SW tank, need to know about the goodies

i went to dr. foster & smiths sight looking for "live rocks" but what i found was it looked like large rocks that would take up a lot of space in the tank. is that the live rock that everybody talks about putting in the tank? and where can i get the right type of sand?

yep "live rock" is just rock that has living things on it (Basicly)
 
ok i'm really confused now. :help: so i should buy live rock? like big chunks? i've seen some crushed coral, is this what you mean or something like it? this was in a bag at lfs ???
