Couple questions after unlocking bootloader (XT1096)

Ok, here's the rundown - I have a VZW Moto X (XT1096). I previously ran mofo on it had flashed the 5.1 img files to it and so had 5.1 rooted, but with a locked bootloader. After learning that JCase had gotten sunshine to work on it I unlocked my boot loader. I then decided that because I was worried about having the a kind of mish-mash of systems on it, i.e., 5.0 bootloader (unlocked) with hacked and modded 5.1 system files flashed from mofo, that I wanted to start fresh. I then used the XT1096 flash to stock script and flashed back to 5.0 (there were a bunch of problems and bootloops and force closes, but I am happy to report I am now on a fully stock 5.0 with unlocked BL). Following being stock I have tried to take the OTA but have been unable to do so. When I try it OTA on my device it just sits at 0%. When I tried using MDM it gave me an error message that it failed to install the update - on the device it said getjar: unlocked.

So, now that I am on 5.0 with an unlocked bootloader I am not sure how to proceed with my priorities, Root, WiFi tethering and upgrading to 5.1. My questions are this:

(1) How can I upgrade to 5.1 or does my bootloader unlock preclude that?
(2) How best can I achieve root?
(3) Once I am rooted what do I need to do in order to enable wifi tethering?

Thank you so much!
