The latest version of Netfabb does comb as well. "Comb" is the name Skeinforge (the slicer that cura uses currently) has for the "avoid running the head through holes" feature.
What's happening here is a bug I think. By default Netfabb 4.9 has a feature enabled that causes the z-moves (when the bed drops down) to happen in random spots on the model. This is done to avoid having a seam on the model. But, I think the comb feature bugs out when it does this which makes it move through the middle of the object. This is also what is causing those tiny bumps.
This can be disabled but I'm not currently at my slice-computer so I can't tell you exactly where. I'll get you the details once I get home from work unless someone beats me to it.

Looks fine to me. I don't know if netfabb routes the travel moves around holes but i would guess not so that's why you get stringing inside. Try printing something bigger and more complex, and try slicing with cura/skeinpypy as well (that program routes around holes).
