There is no way to tell, of course, without determining the structure experimentally and comparing it to the model. Model assessment methods can give you an idea (or the sequence identity is a crude guide).

No. Each restraint (say, for example, a given Calpha-Calpha distance restraint) incorporates information from all templates. Refer to the Modeller 93 paper for full information.
