Best way to set up todos for orders and to print labels as well.

What is the best way to keep track of new orders from customers (I sell
books) and then print labels to ship their orders?

I have used ACT! in which I simply create todos and then access the task
list, print the labels and close the todos which leaves me a history in my
notes.

What is the best way to do the same thing with BCM? Do I work from Tasks
and then Opportunities?

I already have an Aladdin add-on for printing labels directly from the
contacts.

HELP?
