I am not sure about the driver problem but I do know there was a thread dedicated to driver issues and they mostly stemmed from people that had plugged their stock NT into their computer, then had problems when they later tried to use the other drivers for the root procedure. It seems like there were some steps for removing the drivers but the consensus was that it was best to do the root procedure on a computer that had never had a NT or Nook Color connected to it before. Of course, this may be a little hard if you have access to only one computer and decide to root after you've had your Nook for a while.
As far as your Home button issues, I can't say I've had a problem there or know what caused yours. It may be due to you using the Honeycomb launcher. It seems like it gives you the option for about three different launchers. I don't remember what they all are but after reading reviews and opinions, I decided on the GO Launcher EX. The root process also installed HomeCatcher which is a little app that tells the NT what to do when you press the Home
button twice. When I press the Home button twice, I get a menu that has two options. It says "Complete action using" and there's a HomeCatcher icon with no text beside it and an Android icon that says Home. If I press the Android icon, I get taken to the original B&N Nook Tablet Home screen. If I press the HomeCatcher icon, I get another little menu that says "Go Launcher EX" and Home. If I press the Go Launcher icon, I get taken to my Go Launcher Home screen. If I press the Home button once, I get the normal Nook Tablet menu that pops up from the bottom of the screen, regardless of which Home screen I'm on.
The only other issue I see with what you said is when you said you had an issue, so you restored. My concern is, did you unroot before you restored? I had a similar issue and restored without unrooting first. Everything looked and worked like a stock, just-out-of-the-box NT until I tried to root it again. The process would start and then tell me that my NT was already rooted. So, even though it looked stock, technically, it wasn't. Also, I couldn't unroot from that point because the restore process had removed SuperUser privileges from my NT. Whew. If you think that sounds familiar, I think I can help you get through that the same way I did, so let me know. It isn't the end of the world but it's a little more involved. I think I can remember what I did and step you through it.
I too found lots of restore procedures. Some for the NC, some for the NT. Some consisting of the rest/restart eight times in a row procedure. None of them seemed to work well for me and I kind of put together my own from several sources that works well. I'll attach it below.
Good luck.

Please follow the steps below to hard reset your NOOK Tablet.
