Note gross weight. Consider this when you start loading the plane. If you have an empty weight of 400# you have a useful load of 430 pounds - fuel with your extended tanks will be 180# leaving you with 250# for people and gear.
The Covering you mentioned is excellent but will be costly. Consider uncertified fabric and acrylic paint as the lightest and least costly of covering/finishing. see this http://bcove.me/hkevu2sh - BTW there is no latex in latex paint - it is all acrylic and should be called home acrylic paint for your aircraft
You are on a steep learning curve, Welcome
