Simple Layout with proper TW dock icons:

</favorites>

You may change the "launcher:className" & "launcher packageName" according to your choice.

Changing default Internet Browser

if you are using Boat Browser as default Internet Browser, change this,

<favorite launcher:className="com.android.browser.BrowserActivity" launcher:packageName="com.android.browser" launcher:container="-101" launcher:screen="4" launcher:x="4" launcher:y="0" />

to

<favorite launcher:className="com.boatbrowser.free.BrowserActivity" launcher:packageName="com.boatbrowser.free" launcher:container="-101" launcher:screen="4" launcher:x="4" launcher:y="0" />

Changing default Dock Apps

if you need to replace Messaging & Browser with Gallery 3D and Camera (This is for TW Gingerbread; Use proper Classname and packageName for other builds)

Replace,

<favorite launcher:className="com.android.mms.ui.ConversationList" launcher:packageName="com.android.mms" launcher:container="-101" launcher:screen="3" launcher:x="3" launcher:y="0" />
<favorite launcher:className="com.android.browser.BrowserActivity" launcher:packageName="com.android.browser" launcher:container="-101" launcher:screen="4" launcher:x="4" launcher:y="0" />

with

<favorite launcher:className="com.cooliris.media.Gallery" launcher:packageName="com.cooliris.media" launcher:container="-101" launcher:screen="3" launcher:x="3" launcher:y="0" />
<favorite launcher:className="com.sec.android.app.camera.Camera" launcher:packageName="com.sec.android.app.camera" launcher:container="-101" launcher:screen="4" launcher:x="4" launcher:y="0" />
