I agree with the Performance that doesn't need an instrument (such as singing), grab a big weapon and a whip (you got the proficiency for free and it's quite good for using maneuvers without spending feats).
Other than that, your spells won't have good DCs, so focus on buff and utility spells; your normal Bard abilities will also be pretty lame, so the Arcane Duelist
archetype helps with that and possibly mix in some levels of Dragon Disciple
as well if you want to stay "only" a Bard instead of dipping in a martial class.
EDIT: Is your race set?
If not, you could use it to improve your Cha a bit, or maybe grab Half-Orc or Half-Elf for a decent striking weapon (probably a Falchion), I think that Half-Elf is slightly better for Arcane Training.
