The mm parameter, as I understand it, doesn't really play with phrase. So you're looking for the phrase "this amazing sample query", "amazing" must be in the phrase.
and phrase slop reorders things, counting the reordering as "slop", so the approach would not do what you want anyway, i.e. "this amazing query" would match "this query is amazing" if ps were >= 2 (or maybe three, I always have to draw the picture again). I don't even think the mm parameter applies at all to the pf clause, it's just used to boost relevance. You may be able to use the SurroundQueryParser, which is available in 4.0 see: http://wiki.apache.org/solr/SurroundQueryParser but note its limitations.
