[Q] New Z1 user looking to root / flash, etc topic

Evening all.

Have just upgraded my phone to a Z1, C6903 running 4.3

Im looking to root this, mainly as I want to access my SD card over WiFi.

I have rooted my old HTC OneX, my old LG Nexus 4, and many other phones before however the guides for this phone seem a lot more complex, so;

I guess my question is, Is there a way that anyone knows of mounting the SD card to my PC or MAC via WiFi without rooting or ;

Are there any step by step rooting guides (not bothered about flashing a custom rom, just obtaining root)?

Apologies if this has been asked a million times.

Cheers
