Live rock and a DSB will take care of most of the filtration. You will need quite a lot of rock for a tank that size tho. Most suggest about 1 to 1.5 lbs per gallon. I would also get a good protein skimmer and if you have the means set up a refugeum.
guess I shouldn't promot another site on here but www.garf.org has good info on how to build a fuge....by the way nice gift! if you ever want to get rid of it let me know!!
