HazelNuts, the great majority of gliders carry water in their wings only, but there are a few that have tail ballast as well. Tail ballast does affect the AoA and therefore the L/D.

Usually, but not universally. Some high drag, low performance aircraft when at MAUW move so far along the basic polar curve that the ideal L/D can occur at above Vne. However for 99% of aircraft...

But it does. At a higher wing loading the same lift drag ratio (glide angle) is obtained at a higher airspeed than for a lower gross weight.

Think about the vectors involving thrust, weight,...
