car feels slow when the tank is full?

^Yep, gas weighs a lot. I always keep my tank around a half tank or under just to keep weight down a bit.

You are promoting rust and condensation in the upper half of your tank, then.

Not when the fuel is constantly getting sloshed around during driving, that can't really happen. Unless the car is going to sit for a while, then it absolutely could promote condensation and rust.

gas is lighter than water
