First I back everything up... that's key

Then I just hack away completely regardless of any convention or methodology.
Then when I'm done I look at all the files that I modified (sort by modified in Windows Explorer) and compare those to the originals that were backed up. I use windiff.exe, which is a completely free program from microsoft, although there are much better tools out there. I'm told that "Beyond Compare" is better.
Anyway, windiff looks at the two files and shows you how they are different... that way you can get a glimpse of just what the hell you were doing as you were hacking away blindly
