Go into the dev section for the EVO here and download the stock Rom. It's the same thing as the OTA. I just did the Rom and left the kernal and radio alone. Everything is working for me so far.

I am going to post this in the Evo section as well but here a rundown. Hopefully this will answer most of your questions:

Brief OTA flash guide:

Do a nandroid backup (A must!) before flashing a new rom just in case. Enter recovery/backup & restore/nandroid backup/ backup up boot, system, data, and wimax/perform backup.
Download one of the rooted OTA releases. Here is the one on our site: http://forum.ppcgeeks.com/cdma-htc-evo-4g-development/144214-new-stock-gingerbread-rom-4-22-651-2-6-3-2011-rooted-either-odexed-deodexed.html Select odex for pure stock, deodexed for a themable rooted ota. Put the file on the root of your sd card.
If you want to backup your apps and settings etc, do this before performing a full wipe. There are many apps available that can perform the backup (Titanium Backup, Superbox, etc).
Go into recovery again, Recovery/Wipe/wipe All user data/factory reset, Cache, Dalvik cache. While still in recovery, flash the ota rom you saved to the sd. (recovery/flash zip from sd card/choose zip from sdcard/and find the zip you saved to flash) Reboot.
Give it time to setup, should take a bit of time especially on the deodexed rom.
Once you're up and running, you can flash the updated firmware if you choose. It’s not required. However the latest firmware will update your radio, pri, etc so it’s probably beneficial. There are a couple firmware updates available; the first is in the thread I linked above. You can flash this through hboot/fast recovery. Basically by powering down the device, holding the volume down button and power at the same time to enter bootloader. The file will be recognized and ask you to flash it. OR you can flash Calk’s all in one zip through recovery (same as flashing the rom) I did it this way with zero issues. Here is the link: http://forum.xda-developers.com/showthread.php?t=715485 Follow the prompts on the screen if you choose this installation. It will ask you to reboot at which time it will flash the radio update so be patient.
Enjoy your newly updated device. hope this helps.

Couple additional notes:

*I use amon recovery 2.3. I am sure clockwork recovery would be similiar but I cannot say one way or the other. I'm just mentioning this since I can only vouch for my experience with amon.
**You also asked about unrooting the phone but then mentioned adding a rooted ota. I would not unroot to just go back to a rooted status after updating. You will have to wait for another root solution if you unroot and update. So its best to just flash the rooted version.
***I used quickboot(on the market) to easily enter recovery. You can also enter recovery by powering down, holding the volume button down and power button. Hold the volume button down for a few more seconds. Once in bootloader, select recovery.
