assuming you still want to talk your way out of some of the fights i'd start with Bard [for the skills] and 14 charisma ... then id alternate between fighting classes like fighter, paladin , ranger & support classes i.e, Wizard, druid, thief, sorercer to keep my 'to hit' chance reasonable
you will only have level 1 spells, medium armour and i'd play it as a straight up fighter... you will not get any feats so it may be worth considering the grub in your head story line but another true evil character could take druid as level 2-3 [getting the shop discount] then side with the drow to kill the grove and basically get all your sold items back to sell again
