I recommend an oversized filter, esp if you are doing HOB. I would just go with standard media. No reason to waste LR going into your filter, just make sure that it stays clean. You might want to consider running purigen in your HOB.
I wouldnt use freshwater sand unless it is aragonite.
Powerhead might be good, but check your flow first, no reason to spend money if you dont need to. Vortechs are cool, but based on the sounds of things you arent really trying to buy the ritz with this project.
