The wet-dry should work well for a fish-only system, although you might have enough live rock that you don't need it. 70 lbs isn't a lot, though, depending on the number, type, and size of fish you add.
The bio-balls often seem to lead to higher nitrate levels, which don't much matter to fish.

Leave the rock in there, but add some more. If there are fish and other inverts in there, add the rock slower, like a piece every couple of days or something like that. If you were to just plop 50 lbs of new rock in there, it could cause your tank to cycle, thus causing many other problems. Leave the wet/dry with the bio balls if you only have fish. If you want to start adding corals, you may want to consider removing the bio balls and turning the wet dry into a regular sump.

What I meant was that you might have enough live rock that you don't need the wet-dry.
I would be careful about adding more rock if you have animals in the tank. I would actually set up a separate curing tank or tub with a heater and a powerhead and treat any new live rock there before adding it to the tank, although if you add small pieces, the odds are pretty good that you don't have any problems.

The putty is probably safe although I am not sure how effective it will be with the rock. I think most use PVC, wire zip ties, etc... when building the rock structure if they use anything at all. I would not scrub the live rock. If you do that, why spend the money on the live rock? If it is fully cured i would simply add it to the system. That is what I have done twice now and it has worked well fo rme. Just my opinion.

The putty is safe, IME, but it doesn't stick well, so the comments on PVC, etc, are good ideas. You could scrub off any rotten-smelling detritus (dead animal), but I wouldn't otherwise bother scrubbing the rock.
