Default RUU & OTA Questions

My One is S-OFF & rooted w/ TWRP recovery. Still running the stock ROM but have edited some system files and deleted some system apps. So the 4.4.2 OTA won't install. I've read that I can install the 4.3 RUU then the OTA and just flash TWRP & SuperSU again and I'd be good to go. But I have a few questions before I do so.

I used Firewater to S-OFF. With the temproot method, I didn't unlock the bootloader through HTCDev first but it was unlocked when Firewater was done doing its voodoo. If I run the RUU and the OTA will the bootloader be replaced with a locked version? If so, are there any issues with unlocking it again through HTCDev? I've read a few posts stating that HTC no longer supports unlocking the bootloader on AT&T devices (not sure if that's accurate, though). Being S-OFF, do I even need to worry about unlocking the bootloader? With the Inspire, I was S-OFF for a couple of years before I upgraded to an unlockable bootloader. But I never really used fastboot commands to flash any of the stuff I did with that. It seems with the One, most stuff is done through fastboot. Will I still be able to run all the fastboot commands that I would need if the bootloader is locked?

If after updating I decide for some reason to go back to 4.3 and restore a nandroid, will the firmware updgrades from the OTA remain? If they do, are there any compatibility issues when using newer firmware with the older ROM? (I'm still not entirely clear on what constitutes "firmware".)

Thanks for reading my ridiculously long post. Always appreciate the help as I try to figure out all this stuff.
