First, your exalted hero is illegal, his max magic item limit is 50 points, and you have 60 points
just a math error probably
Banner of Wrath never works for me, but if you can get it to work, more power to you
Some Marauder Horsemen for baiting as well as setting up charges for your Knights/Warriors
Marks for your units? Mark of Nurgle is really nice for your marauders, -1 to hit with shooting and -1WS in close combat is really nice for them, and i find that light armour can really save your marauders especially against a bunch of archers
