Your TWRP issue is likely a compatibility issue. If you are using version 22.214.171.124, that version is not capable of flashing KitKat 4.4.x ROM's due to changes in the code from 4.3.x to 4.4.x. Version 126.96.36.199 is supposed to be compatible for KitKat, but a lot of users, myself included, could not get it to work properly, nothing would mount in recovery, and the touch response was horrendous. I personally highly recommend Philz Touch recovery, it is based on CWM, but is light-years beyond regular CWM, and is virtually flawless in my opinion.
