Warrior Build Questions.

I'm currently new at these forums and this will be my second thread, so please take it seriously.

I love running and I charge 2K for the entire desert. I use the skills

Healing signet (never use, its just incase)
Sprint
Charge! {E}
Defensive Stance (for when I got by skeleton archers)
Balanced stance (for the worms / rock guys)
Healing Breeze (just incase)
Mending (Makes the run alot less risky)
Holy Veil (There's a small chance the skeletons will slow you)

My gear is:
15K Platemail Hands, Feet, Head, Legs
15K Glads Chest (I like the shoulder blade and the +3 energy)
Req. 7 aegis -2 Stance / -2 Enchanted(covered by mending)

I have sup absorption on Chest and sup vigor on legs.

My questions are:
1) Is my build capable of running anywhere else where I am able to gain MORE than 10K a run?
2) I've been reading about ascalon gear doing -2 "universal" dmg reduction and sup absorp doing -3 "vs. Attacks"; they both say non-stacking but since ascalon is "universal" and sup absorp is "vs. Attacks", will they stack?
3)If you answered #1 but know I need a few changes to my build, please post them.
