Ok. I'm back.
While I was reviewing all the diff plugins and methods I've tried I seem to have stumbled on a combo that works. (Thanks!) One of the probs is that I can cram all the custom field data into a post I want but then I have to hack the theme to get it back out. That is what I wanted to avoid.
I found a plugin that allows building custom field templates. There's a bunch of them. This one seems to work. You can build a template that drops down under the wp post/edit area and just fill in your handy custom fields. These fields get saved with that post.
Now, it just occurred to me that one of the php exec plugins I've been playing with would allow me to pull that data out of the post custom fields. By executing a little chunk of php in any post that contained my post custom field template I could display it in the post automatically.
So here's my solution:
More Fields plugin to build post/page custom field data templates:
http://wordpress.org/extend/plugins/more-fields/
Include It plugin to exec php inside of a post or page. To use Include It you simply place a tag such as:
[include file=/pathto/yourphpfile/yourphpsnippet.php]
This pulls whatever file you specify and inserts it in place of that tag in the post. Text, php, html whatever. I just create a snippet of php that would normally be stuffed into my template into a text file. Seems to work.
Include It:
http://wordpress.org/extend/plugins/include-it/
Here's a link to some urls I found that discuss wp as a cms:

I wanna thank you for getting me to go back to this problem and see it in a different light. Perhaps it was just a nice time interval between techno frustration and you that allowed me to solve my problem. These two plugins are not the only ones out there of their respective types. I needed a custom field template plugin and a exec php plugin. I found these two. Browse around.
Hope this helps. Your mileage may vary.
