you measure a powerhead by the gallons per hour (GPH
) that it pumps. You will want more than one.
probably won't need the canister filter either (with a DSB
that will be all the filtration you need)
without a sump, you'll want to get rid of the glass tops. See if you can find some "eggcrate" to use as a cover instead. the glass tops prevent adequate airflow over the tank, which hampers the oxygen exchange.
you won't want the airstone either. I say, if you can, turn in the canister filter, glass tops and airpump/sirstone and buy a couple more powerheads and some eggcrate.
you'll want enough powerheads to give you about 500+ GPH
to give you adequate water movement around the rock and surface of the tank. 2-3 PHs would work well. One directed across the surface of the tank will help maintain your oxygen, and a couple more to clash in the middle to give you some decent turbulance. You want this to keep detritus and other waste from setteling and collecting in "Dead zones"

you'll find a lot there on the nintrogen cycle, cycling with raw shrimp etc.
Add in your play sand, put your "live sand" on top of that and let it settle while you go get a couple more powerheads (your tank will be cloudy for a while, get a plastic turkey baster for blowing the sand and silt off of your LR
). Go to the grocery store and pick up a small, fresh, uncooked and never frozen shrimp. Drop it in the tank and follow the directions in the article above. In a couple weeks you'll be ready to start quarentining your first couple of fish!
