Thank you for the instructions, I have tried this, without any luck.
I can get to 4.4.3, but always with corrupted display.
Install 4.4.2 RUU via fastboot. (RUU from Link
Boot into Android.
Reboot to fastboot
Install recovery.img as listed in your post.
Reboot into Android.
Install OTA through Android.
This stuck me with the graphical errors (although the install went smoothly).
I then download the OTA file, placed it in downloads and ran it manually from the recovery menu.
I feel like I might be missing something obvious, but the process seems quite simple, and I've been on stock recovery for quite some time now (was able to OTA the 4.4.2 when it came out).
Anyways, thanks for your time and effort all the same, I think I'll just keep with 4.4.2 for now.

As I was typing this, the launcher came up finally. I also had about 1/3 of my apps removed, and am getting graphical glitches. So, time for that stock recovery!
Oh, also, my power button won't turn the screen off.

For this to work, you need S-OFF and an unlocked bootloader. It also stands that you are running GPE 4.4.2 (or have just updated to 4.4.3 and are having this problem.) This does not apply to any other ROM/RUU.
Download the latest GPE recovery from the first link; http://d-h.st/2F9. For ease of use, rename this file to recovery.img.
Also download the 4.4.3 OTA update from the second link. Put this on your phone's storage whenever you can.
Plug your phone into your computer via USB, open a command prompt, and type adb reboot bootloader
Once your phone reboots and you get your bootloader menu, type fastboot flash recovery recovery.img (it's the stock GPE recovery file you downloaded before.)
Reboot your phone.
Let the phone boot up, then type adb reboot bootloader again. Now, choose recovery to enter recovery. If you get any error (such as a KO'ed Android with a warning symbol above his head) hold VOL-UP and press the power button. You may need to do this multiple times. Your end goal is getting a menu, and you need to choose "apply from phone storage"
Find the 4.4.3 OTA file you downloaded before (the large ZIP file) and select it to install.
You should be done and good to go at this point.
I'd also like to add that TWRP was indeed to blame, as can be the case when OTAs come around. Using the GPE stock recovery got rid of the graphical glitches and slowdown. Now to just redownload the apps it decided to remove :P
