You (or Chilton's) are over complicating this - focus entirely on the timing marks available to you that makes this *really really easy* and ignore everything else. Throw away the Chilton's manual (the time spent getting it, turning the pages is life wasted and they're a liability as you can see here), forget the phrase "TDC" for this job, put the camera/cell phone away and use the marks on the crank sprocket and cam sprockets:
This is so, so, so, so easy - from where you are right now:
1. Line up crank mark
2. Remove belt
3. Line up cam marks
4. Install belt
Done
*If you're uncertain which marks to use - just google it and do an image search. I've never done it but I can guarantee there's about 10 zillion hits.
Steps 1-4 I can do from start to finish including all the serpentine belt, timing cover removal in 45 minutes. Add a little for a first timer and it still probably doesn't take much longer than you've spent looking at Chilton's and taking pictures. Focus entirely on the marks and just get them to line up before you install the belt. For that matter instructions on doing the belt are everywhere as well.
Once you install the belt - if the marks don't line up - wash-rinse-repeat and try again.
I don't install the lower passengers side timing pulley until the belt is installed, it can be installed after the belt is on.
