I never have had a glass top or canay on my tank till I got the MH lighting. Then I had to build one for the tank.
Yes you should have powerheads. They produce the current in the tank. If I remember right its good to go for at least 20% of the tanks volume. In gallons/hr. I have 4 power heads 2 are placed in side the rock strutare and 2 are placed in the top corners of the tank. But placement is all up to the owner and how he likes it.
