Heh, well, you do have those ranks in the all-important "Perform: Pelvic Thrust" you seemed to grow fondness in. Also, it's not like you'd be weak - especially the Dervish, the Rogue, the Druid and the animal companion will all be a billion times stronger thanks to your presence (since Druids aren't good enough otherwise). All in all, I'd completely disagree with Maximiano's assessment - with a party like that, Bard bends Factotum over.
Anyways, with all skills trained, sky is the limit. You have UMD and UPD to an acceptable degree (especially given your Charisma-focus), which means you've got access to effectively all magical effects. Prestidigation someone's shirt red and Bluff them into believing they're the obligatory red shirt fodder, and Diplomacy him to do whatever he wants to do before he dies quick before the red shirt catches on to him.
Use Forgery to generate hilarious commands from whatever master they serve to any dungeon monsters you may encounter. Heck, why not with city guards too? Like, have an order clearly state that they are to moon towards the sun for the first half an hour of the sunrise - a convenient break to enter the city.
Use a combination of Diplomacy, Bluff, Disguise and Appraise to convince some traders that their goods are illegal and to be seized by the authorities (you) immediately.
Roll a Knowledge-check on everything. After all, you are trained in every Knowledge. Also, don't forget to use a different perform skill each time you Inspire Courage (or use any Perform-skill that isn't related to the check result). Perform: Poledancing could be quite the idea, for example. Just carry a 10' pole in Heward's Handy Haversack just for that.
Don't forget all the Craft-skills you've got. You can literally make everything. Like ashtrays and baskets. I'm sure you'll come up with creative uses for those.
Oh yeah, don't forget that you've got all Professions! This includes Gambler, Astrologist, Sailor and many, many more. Don't forget to precede everything you do by saying "I'm a professional!" Also, don't forget to spontaneously start reading peoples' horoscopes once you arrive in a city and taking fees. While gambling.
