First problem: Yes, there are two of them. I just followed my own instructions and it worked perfectly, and I found both instances of the code. Make sure you're using clean copies of the templates. And the instructions were built on 6.05 templates.
Second problem: I just fixed the instructions to use better line breaks that copy over correctly, and also another problem with forum_summary. It should work now. I've followed my own instructions several times now, and haven't found any problems with it.
Start over with clean templates and it should work for you.
