With NURBS, your UVs are closely tied to the topology. The advantage is that you don't have to create a UV map separately like with polys but that you get the UV map for free, automatically. The disadvantage is that you have less control over how the UVs are arranged. Holes can happen when you build your model from unstitched NURBS patches. The DP...my roommate is subscribed to it and I have a few issues of it too. But I never found that it had that much interesting information, it doesn't go deep enough for my taste - some of the reviews sound almost like press releases.
