Buy cured if your tank is up and running. Since it will eb a new set up I'd save some cash on uncured rock and let the whole thing cycle for about 2 months. You can generally find cured Fiji for about $3 a lb so you probably won't see much of a difference in prices on cured or uncured Fiji.
Keep in mind tha clowns can be very territorial as they are just damsels. You might pull off another goby like a firefish with them. Anything more would be pushing the system itself. I'd really look into getting a bunch of small gobies so you can see them interact with each other instead of just sitting on a piece of coral or an anemone. I always suggest a clown/pistol shrimp pair for small tanks.
Okay, clowns, inverts, live rock and sand. I will probably do that. or just do some sort of freshwater community. I would like to try saltwater though.
1 last question - How many pounds of live rock should I get for a 29 Gallon? 20-40?
