Root Restoring a rooted G300 to factory

[Dazg300]

I am replacing my G300 shortly and wish to put it back to factory spec.
Since I've owned it I've....
updated to ICS
rooted following this How to root the Huawei G300
installed AntTek and frozen the bloatware etc.

So,what's the procedure for reversing ?
Unfreeze the apps
unroot ...how do I do this ?
remove any accounts with personal data like gmail,play store etc...will a factory reset be enough ?
cheers

Unroot: Uninstall su and BusyBox.

Factory reset will remove all personal data.
