I think the values are pretty well balanced in terms of points, so that you're not likely to be gipping yourself by not min/maxing "good deals". So you should be fairly free to design abilities to fit the way you want to play.

One tip is to be careful not to lower Happiness or Environmental Resistance too much, and even consider raising them a bit, because it can be much harder to deal with unrest, especially because troops don't help in Proportions. (You can stick a bunch of cheap "civillian" ships in orbit, but that takes more effort and costs maintenance, so there are limits).

Trade is also very important, so minimizing political savvy may not be a good idea unless you plan on having few trade partners.
