Stay in Kunark until 17. XP in Kurn's Tower and it will go quickly. Save up all the bone chips you get to sell in EC and try to buy a Wu's Quivering Staff for 50-100pp. You then might find it easier to do the
Neriak Red Wine quest for faction/banking in the old world rather than trying to up your Freeport faction. Also keep in mind that, especially as you get higher and can survive a few rounds of melee from the guards, you can bank anywhere with the combination of sneak and FD regardless of faction.
