You cannot unlock the bootloader. That is out of question.
To root, look in the dev section, you'll find the thread to root xt910.
As for recovery, you will need safestrap for kitkat ROMs. It is also in the dev section. Along with installation instructions.
Just make sure you use the 'umts_spyder' one.
