Vampiric is superior for damage over sundering. You'll also want to keep a zealous and elemental weapon.
Luck of the Draw is never a good choice for a warrior. I don't know why the wiki page would suggest it as a "great example". It's only half as useful as -2/stance. The +10al vs <element> ones can be great picks but require you to pay attention to damage types and set up multiple shields.
Swordsmanship rune goes on the helmet so that when you swap weapons you only have to swap that piece. Other runes can go wherever. I'd probably opt for a second vitae over clarity, though it likely won't make a difference either way.
I suspect the radiant insignia were from you mistakenly believing that more energy = energy management. Sentinel or sentry would be the default choices.
