I had a tank of gourami, with an UnderGravel Filter and a sponge filter on.
In it I had a mix of pairs of dwarf gouramis. As my final pair I bought some
honey dwarf gouramis. when selecting the pair, I noticed that one of the
fish in the tank had, what I thought, was a cloudy eye. I asked the fish
store guy but he said no its fine, so foolishly I bought a pair anyway. I
plopped them in the tank with the other fish (no I didn't quarantine them
=( ).

It could have been old age, because there was no outward sign of illness on
him and its been about two months since I had the problem, but I'm not sure
it was just old age. I would like to restock the tank, but I was wondering
if I should empty it and scrub everything down, with either bleach or
boiling water and start again from scratch?

The problem with bleach is getting rid of it, you need a LOT of washes.
Boiling water might crack the glass and I'm not sure what it will do to
the silicon. Emptying out the tank, cleaning everything and spreading
the gravel out and letting it all dry might do the trick.

And NEVER go back to that LFS, any owner who will give you such bad
advice is not worth trusting ever again. As for quarantine tanks, I only
have one tank and have never had a problem. Though I look over any fish
in the tank very carefully before buying and ask how long they have been
there etc.
