OK, just select them with select_loop_atoms and use loopmodel.

Sorry, I don't understand this question. All Modeller models are refined by simulated annealing, so there's nothing special about loop modeling in that respect. The main difference between the construction of comparative models and the refinement of loops is that the latter turns on a statistical potential for nonbonded pairs. This is helpful in regions where you have no template structures to provide this information.
