The NAMD manual, and even the tutorial, would only cover the technical
implementation details. As for what approach is better for your particular
case, you're in charge.
There are a few techniques that are known to be "better" in nearly all
cases (velocity-Verlet time integration, Particle-Mesh Ewald
electrostatics) and are therefore on by default, up to the point that you
may be even unaware of their presence (are you?).
For any biased-MD protocol, some help may come by comparing your case vs.
other published studies. But you do need to understand the theoretical
foundation of each method, and familiarize yourself with the user interface
of each software piece.
Try again the tutorials page, as well as the following:
