Default [Q] Root on Cyanogenmod 11

Hi everyone,

I got a Sony Xperia Z tablet LTE (Model SGP321BR/B), and successfully unlocked and flashed CyanogenMod 11 (11-20140301-NIGHTLY-pollux). Is this possible to root the device? I've seen a couple of tutorials on other threads, but they mostly used 4.3.

Could anyone please put me in the right track?

Another question is about cellular calls (not VoIP). Is this possible, using this tablet and this particular ROM?

Thank you very much for your attention.
