This is so far what I could find. Most of the titles are self-explanatory, but a couple such as the Rahls article refer to general issues and are good outlines of obstacles in interstellar flight. Most intriguing are the first two sources, which refer to highly possible methods of propulsion. Josh, the article by Charles Stross may help you out as far as pointing out a potential obstacle to colonization and by extension terraforming.

The first two sites are more public-friendly. They both explain somewhat simply what constitutes cold fusion and how fusion reactions in general work. The next two go into depth as to what is cold fusion and the technicalities behind it. The last one describes an experiment which may or not constitute cold fusion.
