You've got that right. Just be carefull, 66 IS ADDICTIVE.
When my wife and I cruised the Mother Road in 2006 from Chicago to LA, we used Jerry McClanahan's EZ Guide to Route 66 and David Wickline's Images of 66.
David's book consists of pictures and captions of the places you'll be seeing. We had people sign the pictures as we went along for an added bit of enjoyment and memories.
If I recall, Jerry's book also is west to east as far as directions.
Have a great time!!
