just took a quick look at your fighter.
you should get some backup gear maybe. so you have a tanking and a dps gear. for dpssing i'd go for more hp and less ac. so get a minos, a +6 con item and gfl if you don't have it already. use a +5 holy of pg twohander until you have all 3 twf feats (if you plan on taking those anyway).
for tanking purposes a minos would be good too. a +6 con item and a gfl item. ac + hp = win. try and move the intimidate to ring or get a maenya's iron fists gloves.
you can still intimidate while dpssing. more hp will help you there and makes life easier for your healer.
as wf you could have with lvl 16
20 base
140 fighter
12 rogue
112 con (assuming 14 starting +2 enhancement +2 tome +6 item =24 con)
20 toughness (minos)
18 toughness (feat)
30 racial toughness
30 fighter toughness
10 argonessen favor
30 greater false life

edit: oh, and lay off the power attack enhancements for later maybe if you taken em already
