Played this scenario this past week. My party was 2 fighters, a paladin, a rogue, a bard and myself (wizard Blaster). We were a rather diplomatic party we talked (or intimidated) almost everyone in the scenario into doing what we wanted
When I started Second Darkness I began using a VTT (Virtual Table Top) program. To better help me prepare for the game I bought the pdf of the map folio. Most maps (with a little tweaking) work and it is nice to have all maps in one file to pull from when I am setting up the game instead of having to scan the book.
