I would avoid the lavarock, I tried it out for my flowerpot project and it clogged and just got nasty and any miss step I was dumping nasty black water into the tank. Scrubbies are your best bet.
Backgrounds are very easy, I built 1 out of foam and concrete/grout and turned out fantastic. I did 2 layers of cheap concrete and then 2 layers of colored grout and looked better then anything I could pickup in the store.
