I havent read through this whole thread, but one tip that I found really useful was to use a length of hose on the spark plug to help thread it.
I just used some 1/4" fuel line.
That gives you and an extension on the plug, and also it wont get cross threaded as the hose will just slip if you dont have the plug threaded properly.
For my 98 Legacy GT, it made it easier to get to the deep spark plug hole.
