No, you don't. You mean canister filter? If so, no. Get a skimmer.

No, he's just trying to make you waste your money. You might want to upgrade your skimmer but no filters are needed. Natural filtration through live rock is best.

There is some merit to a mechanical filter (to remove particulates, use as a carbon filter, or to "polish" the water occusionally), but, yes, as crissy says, it is usually not necessary unless there is some unusual circustance or requirement that led your LFS to give you their suggestion??.
