From one gear head to another, I have no doubt that every thing you said is true, and true about me. A little history:
I started experimenting with Dad's old Ansco 35 mm lever cocked shutter guess and shoot in late 60's. Didn't do too bad. It died on a 4 week cross country vacation. Studied up on every brand of slr and bought a Canon AE1Program and 2 Solarigr zoom lenses. With all the new bells, my average increased. Exit film, enter digital. 2008 a Canon XSi and two zoom lenses. I have thousands of digital images on my computers and memory cards. I also have a few(4) that I have printed, not counting the neighbors wedding last summer. I have lightly dabbled in post processing using a half dozen different programs.
The future: I want to start improving (pp) the photos I have, and will take. But sometimes learning photography here on the Hog is like learning to play golf by trying to catch golf balls at a driving range. Catching bits n pieces, some good, some bad, and ducking the unsure. A good book would help, maybe. I did find Al Judge's series of books on Amazon. I like his style, short, to the point, and no fluff. He started with pin hole cameras and worked up. I have learned something from every book. It seems to me, from reading the hog, that for me, understanding what a sensor, sensor array, and computer does to make a raw file then convert it into a Dnf, Tiff, or jpeg file, will give me that strong foundation to build my pp abilities upon. It's a lot easier to build upon a strong foundation than to flounder around aimlessly, then have to go back and start over, which is what it seems like I'm doing now.
So, if you have suggestions for good books on post processing for beginners, I'm all ears. If the books are Adobe Photoshop specific, I'm going to groan and decline. I'm leaning towards Corel AfterShot and Paint Shop Pro so that I don't have to relie on an internet connection if I'm traveling. The two highest items on my learning agenda are; organizing and workflow. I've been trying to read the DAM book on oganizing, but I get tired of reading fluff. Work flow starts with adjusting the raw file in what program then saving it into which format and why. Then what is next, and why. I know sharpening comes close to the end.
I did hook up with a local club on Tuesday. There seems to be a couple who are strong in pp. I have hopes.
Maybe next time we can talk cars or whatever.

You know, I don't think there's anything at all wrong with trying to understand how a sensor works, but it's really true that it won't be all that useful when it comes to things like composition, or adjusting tone and color in post-processing. It's kind of like trying to understand how to program a spreadsheet by going all the way down to transistors and Josephson junctions. It's really cool when you can understand how analog voltages can translate into two states (false, true or 0,1), or how NAND gates work, but the whole point is to build up a sufficient level of abstraction for the kind of work you need to do. You wouldn't program a spreadsheet in machine language. Likewise, knowing about Bayer arrays isn't going to translate into taking a good photo. You need a different vocabulary.
I suggest starting with:
1. Exposure. What is it? What physical properties contribute to it? How can you manipulate different parts of your camera to get good exposure?
2. Tones. What are blown-out highlights? Crunched shadows? How do you avoid them? (Hint: see #1) What is a histogram, and what does it tell you? What is dynamic range, how can I use it or work around a lack of such? What is a zone system, what does it do, how can I use it?
3. Color. What are primary colors? What are the different color models, and why are they useful? What are complementary colors? How do I use all this to remove color casts, have a pleasing pallette in my image?
4. Composition. There are lots of guidelines, but this isn't really a science. It's much more an art. Nonetheless, there's a lot of thinking to do about what can I do with my camera to augment a strong composition (foreground elements in focus, etc.), balance, choice of lens, creative use of lens distortion?
There are areas where I think some knowledge of sensors is helpful. Things like full-frame vs. crop, low-light performance, noise at high ISO levels. It's my understanding here that the amplification step is what introduces the noise, something like higher ISO means the signal is amplified more, which magnifies the effect of noise, which is always present at some level. But I'm certainly no expert here.
Good luck with your endeavors! I hope you overcome your fear of Photoshop and Lightroom, they're really pretty good at what they do, and you can do a lot with them.
