My recommendation on pair programming is that it is a good idea, you should try it, you should do it 5%, 10%, 20% of the time, whatever you want, I don't think is a good idea to do it 100%. I see two main benefits on pair programming.

  - Knowledge transfer. Learn new and better ways of working. IDE usage, short cuts, etc.

  - On a complex piece of software is better to have two sets of eyes checking everything.

TDD. I enjoy doing it, I am not strict on doing test first, most of the time I don't. I usually shoot for 70% coverage. Indeed, the tests take a significant part of the effort, often they are brittle and you need to refactor them, but I really think they improve your overall design, your confidence on the robustness of the system.
