No exergy, yes.

Force would tend toward zero as the universe expands and everything 
becomes infinitely far apart. Gravity force is inversely proportional 
to the distance squared.  This doesn't mean gravity is weaker, it
just means the distance increases.  Meanwhile the potential energy
increases (to a limit, at infinity) just as lifting a rock increases its
gravitational potential energy.

Had less entropy and more exergy, yes.

Again, not correct, only exergy will decrease.

Also the heat death is a statistical effect, there is no actual law of
nature that requires it, beyond statistics. It's just that when you have a
system of high energy (temperature) stuff and low temperature stuff, the
most likely effect (by far) is both sides become a uniform temperature,
possibly driving a heat engine in the process.

I haven't figured out how the fact that an expanding open universe, like
ours, having constantly increasing (toward a limit) gravitational
potential energy jibes with an eventual heat death. Perhaps it is possible
that a heat death could have potential energy that can _never_ be used as
exergy.

But my point simply is there is no connection between the statistics that
drive toward a heat death and the gravitational constant G. It is a
constant.
