I'd say go for the bard. You don't expect intense combat, so there's no need to max out your combat potential. You can work on the roleplaying aspects instead, and bards have lots of that. You'll get bardic music and cantrips, which have a ton of potential in a low magic world. If there is minimal magic in the world, you can expect any magic to make a big impact on NPC's. Ghost Sound and Prestidigitation both come to mind. Even light could dazzle a crowd, and would come in handy for an all human party in the dark.
Since you have weapon finesse, you use your dex bonus already with the whip, so agile maneuvers won't help any extra with any whip based CM's. There are plenty of good feats to choose from, those listed above are good, or dodge & mobility might suit your character type.
