Shields are dumb. Here is the best I could come up with, assuming you are ok with also having HiPS.

UMD and other notes
All attack bonus calculations should be 2 higher most the time. With UMD and CL 15 heroism scrolls, it is pretty much a permanent bump.
Easy to have +5 to all saves, heroism scrolls and greater resistance scrolls are both purchasable.
Easy to have +3 saves against spells. Spellcraft is crossclass, but able learner and 16 int helps.
Should be able to have at least some ranks in heal. Use it to spam health up with healing kits.
I was too lazy to put the skills in, but you should have maxed (or near maxed) hide/ms, spot OR listen, heal, tumble, and UMD. There should be some odd ranks left over, which you can use to fluff your character with sense motive, lores, or any other fun thing you might want.
I could also mess around, if you dont like HiPS, and do something like 14fighter/11ranger/5tempest. It would net you +2 AB (BaB), +2 when duel wielding (tempest), and 2 AC. It would weaken your saves a little and cut out a lot of feats and skills.
Edit
Forgot critical focus from Whirling Dervish!
