Moon with minimum eccentric orbit

At what Point of eccentric elleptical orbit would the moon cause problems due to raised sealevels and tidal waves?

What is the elliptic Kepler eccentricity of moon 0.7 or less?

Distance at perigee ~362600 km
(356400 – 370400 km)
Distance at apogee ~405400 km
(404000 – 406700 km)

Could the solarwind affect the eccentrity of moons orbit.

Also i would like to know how the eccentrity of orbit effect the visual appearance of moon.

What is the distance and eccentrity when it will appear double radius at perigee, tripple radius etc is there a formula?(maybe a question for physics, but could you answer?)
