Should I paint/waterproof my basement floor?

I am currently refinishing my basement. I painted the concrete walls w/ that DryLoc waterproofing paint before I put up my 2 x 4 walls. I saw the demo at Home Depot and it sold me on it. It wasn't fun to do (that stuff smells) as well as it takes some time but it's done and over with.
Now, the question is what do I do with the bare concrete floor?
I will be putting carpeting in half of the basement w/ a nice pad for comfort.
In the other part of the basement I plan to put Mannington laminate planks that look like real wood. Under this I will use the recommended vapor barrier per Mannington recommendations.
My question is before I do the above on the floor, should I coat the concrete floor w/ one of the special floor paints that also have a waterproofing effect? Or would this be a waste of time and money as the floor will be covered and water does not rest under the floor like it runs on the outside walls????
Thanks in advance for your advice.
P.S. - I like to do it right the first time. If it isn't done right the first time, why bother at all.
