There are a couple different ways you can get a sump. For your first one I recommend buying one over making your own. They are fairly easy to setup and will help you understand how they work, then later if you feel like building one you can. You still havent mentioned if your tank is predrilled, im going to assume no, since you come from FW background. I recommend two overflow boxes, having a back up is always nice, and they will cover more area.
