The best way to improve your BAB (buildwise) as an arcane archer: only take one or two levels of wizard or sorcerer. Anything more and you're tanking your BAB for a rather dubious benefit. Maybe if you could use the battle sorcerer variant from unearthed arcana, you could take five levels and then take a couple spellsword levels in order to get third level spells and the ability to cast spells in your mithral chain shirt without spell failure, but you'd be giving up archery abilities which are your pimary abilities for more secondary or tertiary abilities--and that's normally not a good trade.
