Welcome, bookworm_mom. I like your username and can relate.
The approved foods list is very helpful. In short, if it is a higher fat food like tofu, nuts and seeds or avocados then it is to be considered a treat rather than a staple food.
Are you bringing your kids and DH along on the journey?
Anyway, welcome and come often. This is a very supportive board with lots of experienced people who have great suggestions. If you want, come post your weight in the "Roberta's corner" forum. People who want public accountability post their weight once a week there.
