I don't know your personal progression (Though by your armory page it appears you're in Kara) so I'll to keep the items to a Heroic/Kara/Craftable level.
For bracers, you can replace them with Steadying Bracers (A badge reward). It's relatively cheap, badge wise.
Now if money isn't an issue, your belt can be replaced with the Belt of the Black Eagle. This is a crafted item which requires 2 Nether Vortexes (Vortices?) as well as a crapload of primals, skin, etc. If you didn't know, Vortexes only drop in T5 content, so they usually go or about 250g+ per on my server.
If you don't have the money, there's a pretty good belt from the badge vendor too. War Feathered Loop is what it's called.
As for the boots, you can have a Leatherworker craft you Boots of the Crimson Hawk, though this requires 2 Nethers (Normal nethers this time ^^) to do. Alternatively, you could get the Fiend Slayer Boots off of the Chest event in Kara.
Also, just so you know, on your armory page when you mouse over an item, there's a "find an upgrade" feature which you can use.
