I can't answer your facet questions, but this one I can.  If you are 
using the default relevancy ranking and you do not want the values in a 
given part of your search to affect the score, put it in a filter query 
(fq).  Also, if you are sorting all your search results in a 
deterministic way rather than using relevancy, use a filter query.

If you do want those values to affect the score, which is normal for 
fulltext fields, put your search clause in the regular query (q).  Most 
of the time, a date range is not something that you want to affect the 
relevancy score, so it is a perfect candidate for filter queries.
