* Grab Prehensile Hair Hex!
Now you have 10' reach and you use your INT modifier for those touch attacks.
* You can also use your familiar to deliver touch spells, but I don't like the idea until you have Improved Familiar Feat
* Get Misfortune. It isn't a Mind-affecting ability (Charm and Evil-Eye are the only ones which explicity say "This is a Mind-affecting")
* Ward Hex isn't very strong, but the +2 could help sometimes.
* Use your spells for buffing or summoning, like Enlarge Person on the Fighter, Summon Monster I and flank the undeads, etc.
* Buy a crossbow! It's a simple weapon that anyone with low STR can use.
