Even if the ad doesn't ask you to send evaluations, it is likely to aid your case if you include them. Highlight those that you've already taught. Check to be sure that your teaching interests are consistent with the courses mentioned in the advertisement. Because teaching is so central to the mission of small liberal arts institutions, you should use this section of your application to clarify your love of teaching and the success you've enjoyed to date. If you have a particular style of teaching, you should address that in your statement.
Most applicants have relatively little teaching experience.
If, however, you are a more senior person applying for a position, I would include only the most recent information about teaching in your portfolio. That is, only a few recent syllabi, and course evaluations from the past year or two. For the most part, the faculty writing letters act as though they are recommending you for a university position. I know that you can't control the behavior of your faculty mentors, but try to nudge them to observe you teaching. Their letters will be strengthened considerably if they address your teaching abilities.
