Honestly your Live Rock and your Live Sand will help a LOT! If you feed heavy or have "Messy" eaters (lion fish, puffer) you may want to go with a wet/dry but then again that's not ideal for a REEF set-up. Think long-term and if you even remotely think you may want coral go ahead and plan that way.
If I were you (and this is where I started out as well) I would plan for Reef just in case. Research a sump and a fuge (called refugium).
