What are you planning on keeping? I don't want to be a Debbie Downer but I'm not sure how well that stock Marineland tank is going to work out. I looked at that option when I started as well, since it says it can be used for saltwater. The biowheel filtration and the lights are not suitable for a reef tank though; they are meant for freshwater.
If you have the stock lights you won't be able to keep corals, which may not sound like a big deal right now but a few months from now you might be bummed. Hopefully someone here has experience with this setup and can chime in how they have made it work for them.
Back when I was researching this tank it appeared that people would buy the upgraded lights, about 150 from amazon; and get rid of the biowheel and run a skimmer....
