Well, the Spirit Lion Totem from Complete Champion is a pretty common choice for Barbarians, first. It gives you Pounce in exchange for Fast Movement, which is a solid trade. The Monkey Grip feat can be replaced with a magic item (Strongarm Bracers, in the Magic Item Compendium), and Weapon Focus... isn't really a good feat to take unless you need it as a prerequisite for something else. ^^; Same for Cleave, unfortunately...
Maxing out Intimidate and taking
Imperious Command and
Intimidating Rage can give you some extra versatility in battle, though the Charisma requirements on that first feat might be a little hard to swing.
Power Attack and Leap Attack are commonly paired with
Shock Trooper's Heedless Charge ability, though you'll need Improved Bull Rush to pick up that feat.
The Streetfighter ACF found
here looks like it could be fun, and the 'Skilled City Dweller' ACF on that same page could give you access to some more useful skills, as well.
I'd probably replace the Merciful property on your sword with Berserker, which is in the MIC and 1d8 to damage while raging, or Warning for a +5 to Initiative.
Other than that, though, your choices look pretty good. Most of the above are only suggestions anyway, so feel free to take the ones you like the sound of and ignore the ones you don't. ^^
