After looking at it again, I think I'll keep the spiked shield. While the AC bonus overlaps with Two-Weapon Defense, the shield adds an additional +1 to Reflex, whixh would otherwise be an Achille's Heel for her.If the fighter is a tempest, ditch the spiked shield. She gets Two Weapon Defense for free as a class feature, which gives a +1 shield bonus.
She can gain a feat, a point of AC, and effectively one extra magic item by scrapping both bastard sword and the ranger multiclass to take a double weapon instead. FWIW, urgroshes make good weapons for rain of blows (doubly so for dwarves, but that's neither here nor there).
