First, Welcome to Reef Central!!
Depending on what type of livestock you plan on keeping, you may want to add either some powerheads or a canister filiter for some extra water movement.
The nice thing about a canister is you can use to run carbon if you want to. But that's the only type of media you should use in a canister, no sponges or ceramic rings. You also have to make sure you clean a canister regularly, like weekly.
Other than that, I think your LS and LR will take care of the biological filtration.
