Other than the Markman books, I'm not familiar with the ones your therapist recommended. The Markman ones are good general relationshihp advice.
HOWEVER, I want to caution you against rushing in to "fix the relationship" so that there won't be another A. Affairs do not happen because the relationship is flawed. They happen because the WS uses a very unhealthy way of coping with what are common relationship issues. The recommended approach is that before the general relationship issues are addressed, the A has to be dealt with. Think of it like triage in an ER. If someone comes in with a gunshot wound to the gut (the A) and a sprained wrist (typical relationship issues), the most serious threat to survival has to be addressed first.
Plus, WS's who haven't fully come into remorse (see http://www.survivinginfidelity.com/forums.asp?tid=406548) aren't really in a position to work on the other issues. Defensiveness, blameshifting, etc. get in the way.
Our MC and the kind folks at SI directed us toward a different set of books for dealing with issues after an A. I'll list them below for you.
