Have you tested the water in the trash can for po4 or to see if the cycles moving along?
You cure dry rock outside of the tank incase it contains trapped phosphates. No need to start a huge algae bloom when you don't have to (high nitrate from the cycle + trapped phosphates = algae nightmare).
Op to your power head question, just point them at each other and turn them on. The korillias aren't capable of simulating the currents like your asking, you'd need a jaebo or vortech style pump for that.
You can connect the korillias to a controller, timed power strip or wave maker to randomize their flow.
Everyone has an opinion. Some are better than others. The LFS and books tend to be the same way. Just keep participating and you'll figure it all out. In this hobby there are often more than one technique that can have similar outcomes.
