Another I've been thinking about is Martial Study. Again, I don't believe familiars should get involved in combat, but some options can be funny.

Especially if giving Insightful Strike to a familiar. Sure, it's gonna work once in a fight, but since a Wizard is likely to have maxed out concentration, and the familiar can use her ranks... then even a tiny pecking from the familiar can inflict 1d20+concentration ranks in damage. Can make quite the surprise attack.
Familiars actually become pretty powerful when you are using duskblade where you have the life and bab to really make use of a familiar. Especially if you are using improved/dragon/etc. familiar and in that case they work very well in combat.
Martial Study and Stance are good options and so are feats like Knowledge Devotion that take advantage of the owner's skills. Some of the other devotion feats can also be pretty good ideas. Beyond Giantbane, underfoot combat and Confound the Big Folk can also be great for small and tiny familiars like Musteval Guardinal and Pseudodragon.

Beyond that if you are a spontaneous spellcaster you could also look at abusing spell-linked familiar and bloodline feats from Dragon Compendium
