I think that difficulty refers to 2 things. Grade and Technical features. The grade of a slope will make the ride a higher intensity ride or a lower intensity ride. So if cardio and muscle endurance are a problem, stick with the lower grades/the less steep stuff, but if you have great cardio but less experience or skill, go with something steeper but fewer technical features. Technical features include rocks, roots, single track, logs, jumps.
Now how do you tell which trails have what? I've found that most good books on cycling trails will have an elevation profile as well as a description of the technical features.
One series I recommend are the Falcon Guide books. I have the Falcon Guide: Mountain Biking the San Francisco Bay Area. It not only has a highlighted map of the trail and a step-by-step description and a easy to read elevation profile, but it also has quick easy to read blurbs about difficulty, trail surface, terrain, seasonal info, dog compatibility, schedule, etc, in the very beginning of each section. I've seen other good books out there, but this one is my favorite.
