Debbie sums up the MWL guidelines well in the post stuck at the top of the MWL forum
here. You're right that pasta is a flour product and therefore not part of MWL. However, whole grain pasta is fine in the "regular" McDougall program. Some people lose weight without resorting to the further restrictions of MWL. Some people lose weight combining the two (such as Marla just mentioned in her last comment in the 100% compliance thread). Others must stick strictly to MWL to consistently lose weight.
When first switching to McDougalling and trying to eliminate the animal foods, oils, and too much sugar/salt, I think it's easiest to allow yourself to get familiar with the regular program foods. Then, if necessary, incorporate more and more MWL principles - more raw veggies, more whole foods instead of flours, etc.
