Actually, I found a rather easy way to root from 3.2 over on the XDA forum.
xda-developers - View Single Post - How to root stock 3.2
This link is to the part with his Version 3 files, but it is not the beginning of the whole thread detailing the process' evolution.
The instructions are a little bit confusing. He has issued a Version 2 and Version 3 (which I used) of this method, and it is VERY close to a "1-click root" process. Inside the zip file for V3 there are PDF and DOC copies of instructions, but actually they are only what he CHANGED from version 2 to version 3. So for example the V3 docs don't tell you to install the PC USB driver (which is included in the zip) before you start. I like newb-oriented instructions as I would much rather have to read something I already know than to miss something I did not think of when it was needed. So what I did was also download Version 2 zip file. In that is a document called "Steps", which were the more complete version 2 instructions. Not much was actually changed in the V3 instructions, but Version 3 streamlined and made the process into less steps to do. By reading both instruction docs, I was able to piece together all the complete steps needed for V3.
There are lots of files in subfolders of those zip files in both versions, including copies of ADB and several scripts. That led me to thinking I would be manually running ADB. But in actuality, those are all for his central script to use, and they run automatically. No loading ADB, etc. You just get the tablet connected with the USB driver, obtain its serial number with a small utility included, then run the main script file from your PC and follow its instructions. When it is done, you have a fresh copy of rooted 3.2 (it does wipe everything back to "from the factory" state).
He also includes instructions on how to get and install ClockworkMod Recovery.
Note that it has been mentioned this rooting process seems to work better from Win7 than from a WinXP PC.
Only a one-click process could be easier. Compared to other methods I have read which have like 20 steps, I was expecting to need to do a LOT more, so the instructions just didn't seem sufficient at first. But it worked great for me, once I figured out it was pretty much all automatic.
