Dwimmermount Sources

I was thinking of running Dwimmermount Acks version with my gaming group. I’m looking at drivethrurpg and there are several sources dedicated to it. I’m obviously getting the core book and will probably pick up the illustrations for fun. There are also two sources calls “maps” and “dungeon tracker.” If anyone has those can you tell me whether it is worth grabbing both or whether they are largely redundant?

I have both, but end up using the maps in the Dungeon Tracker pretty much exclusively.
