All right, I am so desperately predictable.
I bought an eye-one display LT and I got a hold of HCFR...curiosity had the better of me and now I am doomed.

I spent 5 or so hours last night getting familiar with the procedure described in this guide: http://www.curtpalme.com/forum/viewtopic.php?t=10457
Prior to that, I made myself watch the entire DVE disc and I also did search these forums extensively to understand the role of the Backlight control and what range should light output should fall in for the IRE 100 window pattern.
And now, tada, here I come back...
My gray scale now seems much better, but I have some questions based on what I saw.
My TV is a Bravia KDL-40Z4100. In use for less than year.
1) After some tinkering, I found that using "Warm 1" for Color Temperature and "Medium" for Gamma would get me better results right off the gate. (by improving both the look of the Luminance graph and the look of the Gamma graph)
2) I also decided to go with "Standard" for Color Space. A PS3 was the source, RGB Full Range (HDMI) was set to Limited, Y Pb / Cb Pr / Cr Super-White (HDMI) was set to On, BD / DVD Video Output Format (HDMI) was set to Automatic.
3) When I started to measure my initial gray scale, I noticed something with the Video Black w/ new PLUGE pattern.
When I display it, my panel is a certain level of bright during the first 1-3 seconds, then appears to dim after that. I do have auto-dimming set to off and I do not see this behavior with the IRE 10 pattern or any of the other window pattern used for gray scale calibration.
Is this normal? Does it invalidate my measurements at IRE 0?
I also have to pause for that pattern because the DVE disc doesn't appear to loop it like other patterns.
4) Adjusting Gain and Bias for R, G, B proved to be easier than I thought. Except my IRE 0 and IRE 10 measurements are not so good with a deltaE of roughly 100 and 12. From IRE 30 to IRE 90, deltaE is mostly below 2.
After calibration, my Luminance graph is practically perfect and my RGB levels appear to be flat on 100% from IRE 30 to IRE 90. My average Gamma reading is also 2.23.
5) Adjusting primary and secondary colors was a lot more difficult.
Setting "100% Red" correctly was fairly easy, though.
Adjusting the secondaries was nearly impossible, "100% Cyan", "100% Yellow" and "100% Magenta" are still quite far apart, even though each ended up in the inner circle of the target on the "Selected color" panel.
6) My set doesn't have a proper CMS, so I had to stop there.
After calibration, I noticed that I was getting above 40 ftL for the IRE 100 window pattern, while I had started at nearly 31 ftL.
Is that normal?
After calibration, I also have the impression I have some color leaking into my gray bars. It was late and maybe my eyes were shot, but is this a common reaction after calibration?
I would appreciate your feedback.
