Well, I wondered if this would be a problem, yep, it is...
Enabling USB Debugging, make's me lose the drive letter in WinXP. I'd discovered that was the reason, I no longer could access the phone by USB last Friday. By that point though, I'd uninstalled and re-installed these drivers ... to finally learn that
ZTE_Warp_Sequent_USB_Driver_EXE_-_4.28MB_
How might I again have USB debugging on, AND have the phone be issued a drive letter at this point?

Figured this out, took several more installations of drivers, re-booting the PC, and, was getting nowhere, till re-installing the native drivers off the phone, after the downloaded drivers, then a drive letter was assigned, now it's on to CWM and shinru2004's rom.
To anyone else, who split's their attention, (as I did), if your rooting, root! If you want to tether AFTER root, first go root, then look into tethering. You see I'd gotten root, then happily re-installed PdaNet, during one of my merry romps in the woods chasing hotspot for this Sequent to Lexus 7. Crap!!! PdaNet, installs it's own drivers over, or in place of junkie2100's advised driver's, (for installing his CWM)
I plead INSANITY!
