Any of these should be fine:

As for the force field, there is no single "best" option.  Each force field has 
its own sucesses and failures.  You should plan to invest significant time 
learning about each of the force fields and deciding which is best for your 
application, based on known limitations and the underlying theoretical basis for 
it.  Choosing a force field is one of the most significant steps in conducting a 
quality simulation.
