4pc Zuni is extremely nice. You could do much, much worse.
My other opinion would be to grab a halfway decent black damage/lifesteal/socket weapon and grab a Tal Rasha's Allegiance with average damage.
Figure Pox will run you 20m , helm will run you 10M (Don't get crit chance, it's very overpriced on the Zuni hat and ring, go for average damage on the ring and 290+ int on the hat) . That leaves you 90M to mess around with to get a nice Tal Rasha's (15M), some 10% crit/critdamage/int gloves (10M) and a good weapon. You could just about afford to get both average damage and crit on the ring if you found a good deal, but you'd have to find a good deal. Remember though that you'll be selling your old stuff at the same time. You could probably do better on the pants (Lose 20 vit for 70 int) for pretty cheap, as well.
Black damage isn't an immediate concern with just the Zuni's trail's 8% poison for you, especially when compared against the good lifesteal, crit damage and socket on the Manajuma's.
As far as bracers are concerned- you'd be losing a significant chunk of int for a bit of attack speed which isn't as efficient for WDs as some classes. It's still better than not having the attack speed, and the movement speed is nice, and you have no other place to get it besides inna's pants... but you're also looking at 100m just for the bracers in that case for something that won't be all that great.
You could prioritize a lot better.
EDIT: Also- your offhand is horrible for the budget of your build. Upgrade to 8.5% crit and better average damage, STAT.
