The character you describe uses basically every single ability score except Wisdom, which has one of the most important standard effects. IMO ditch TWF and Weapon Finesse, and use Crusader since it's not as reliant on Intelligence as the Warblade is. You'll be able to fake being nimble starting at level 2, when you get to substitute Perform checks for Acrobatics checks.
Take these feats at low levels: Extra Music, Battle Caster, Weapon Focus [generic reach weapon], and Lingering Song, and re-train them into more useful feats at higher levels (basically the feats that make your build: Power Attack, Snowflake Wardance, Force of Personality, Song of the White Raven, Versatile Performer, and Dragonfire Inspiration).
Extra Music is just plain awesome at level 1. Bardic Music is basically a casting of either Bless or Charm Person at those levels, which means you essentially get 4 extra 1st-level spell slots for a single feat. It's usefulness sharply diminishes later. Battle Caster is important because your AC will be important at low levels. Scale Armor and Breastplates are cheap and necessary for adequate defense, although later on you'll have the much superior spells Blink and Greater Blink, and AC becomes meaningless anyway, so you can just use a Mithral Brestplate and enhance it however. Weapon Focus is explained below. Lingering Song is useful because these low levels are where fights might last longer than a few rounds.
Stats should look something like this:
Str 14, Dex 9, Con 13, Int 14, Wis 7, Cha 18
Strength 14 is why Weapon Focus is so important. Your hit rolls are going to be relatively bad. Con 13 likewise sucks, but it's going to hurt you the least by being low early on, especially if you use a reach weapon. Wisdom 7 is terribad, but you'll likely get double-Charisma to Will instead of Wisdom, so it's going to be more-or-less completely unnecessary by the time it becomes truly important.
Items to look for:
Shadow Hands (ToB)- Lots of useful maneuvers for this kind of character are Shadow Hand maneuvers, but given that you're going Crusader you won't normally get them.
Slippers of Battledancing (DMG II)- Use a one-handed weapon in two hands for Cha to hit and 1.5x Cha to damage. Skill requirement is meaningless, since Perform [Dance] really ought to be maxed. It easily has the best Versatile Performer effect. Relatively expensive, though, so use a reach weapon for the defensive benefits until you can use this.
Vest of Legends (DMG II)- Great for bards. Better for Pathfinder bards.
Fearsome Armor (DotU)- Lots of ways for PF Bards to get high Intimidate later on, and Shaken is a useful condition to be able to apply to an enemy. Combine with Imperious Command to basically make anything vulnerable to Fear lose instantly.
Late-Game:
You're going to wind up with a LOT of skill points. Consider Knowledge Devotion, since it works extra-well with PF Bards. Truenaming might also be an option, but it will eat *a lot* of feats if you want to go straight-up Bard//Crusader. The ability to throw out on-demand minor magical abilities (or not-so-minor ones if you get something like Fog from the Void) is really powerful if you are able to make the necessary investment in the Truenaming skill such that you don't suck at it.
