Welcome to 3reef first of all!
Now to answer your question: first of all, you don't need to add any kind of cleaning crew right now ,IMO, as you don't have much of a bio-load and you would be better off waiting til your tank gets better established and matures. You will take the risk of starving your inverts if you don't have micro/macro algae for them to feed on or even detritus. Do you have live rock in your tank?
The biggest question for you to answer before goingout and purchasing fish for your fish only tank is What kind of fish do I want to have in my tank? When you answer that question, you can then begin to focus on the inverts for the tank. Some fish will eat certain inverts so you need to be careful with proper selection to match. For example, certain Triggers will eat urchins, crabs, snails and crabs as well as small fish.
There is a book by Scott W. Michaels called "Reef Aquarium Fishes" which can help you with proper fish and invert selection to better enable you to keep both fish and inverts in the same tank!
