I figure the components separately when I do things like that. It's just easier for me that way.
To do the POINTS for your bread just figure the POINTS for all of the ingredients, add them together, and divide by the servings.

will be helpful with the POINTS in baking ingredients. I just used that site today to figure out the POINTS in a Chicken Stroganoff recipe that I found on Food Network. Good Luck!
