DD in this case means Dwarven Defender and you don't need any spell caster stuff. Just note to only take 7 levels of WM / Weapon Master. Anymore than that in WM and it's sort of a waste.
I've figured that out myself (about the WM, not the DD). He sound pretty hard though... But if you really whant to powergame, it should be Barbarian/DD/WM. The only problem is changeing from neutral to lawfull (as far as I know you can only become more good, not more evil or caotic or lawfull...).
