Noob kernal question

[JeffKay]

I gave up my Touch pro for my new Moment. Very happy so far. I have flashed my TP many many times, no worries there. So, I'm new to "rooting" and I don't want to mess it up. A few noob questions..

What is the latest Kernal? I see 14.3 but the wiki ways 14.4? Did I miss the link?

Also, there is a ton of SPH_900 files on megauploads. "update" ones, "patchnoob" ones? Which is the proper link for rooting from a stock CL14 phone?

Is there an easy way to flash back to stock for the upcoming 2.1 update?


Thanks
Jeff
