just make a master save before you go (so if you screw it up you can come back and try again later) and stock up on many healing potions and oils of speed, plus the best armours/weapons you can get your hands on AND, this is important, AMMO, tons of. at least a hundred for each missile weapon, in addition to three full quivers. go for quality here, its important.

in general, if you can beat bohdis guild, then spellhold should be doable.
