As an Erudite Cleric, who's also potbound:

Boon: Cabilis faction is amazing. Nothing like beating everyone else to a target in Kunark because you can start from Cabilis instead of a port-in.

Going so far as to be indifferent so I can shop: A lot of Iksar sell 'useless' research and cultural items so you can find some good stuff vendor mining. You can also buy Maneater Plant Salve. Apprehensive's ok at 134+ CHA, but I went to indifferent.

Runners up: Neriak faction (very convenient to bank, being that "The Dead" are apprehensive to a Quellious worshipper for some reason). You also get some vendors in South Ro, although you can really visit Rathmana, whose shop is safer and he sells food and water and drinks and some reagent gems.

You can generally skip Oggok (just invis out to Fear Portal) and Grobb (you don't even need invis if you know where the line is to avoid guard aggro on the way to Guk).

Bust: I've wasted a lot of time trying to faction up with Brood of Kotiz to no avail. They're avoidable (only 2 mobs in East Cabilis, and avoidable in West Cabilis). Yes I lose some vendors.
