Welcome to the forum! I haven’t yet built the Beacon Hill but I plan to start mine in February-March. As to glue several people use wood glue, especially in the south (because of the heat). I have a preference for tacky glue but also use wood glue. In regard to primer, I never prime the house until the base structure is done-mostly because I don’t know what I’m going to do until the base structure is done (brick, stone, siding, paint etc).
Havanaholly will tell you to read the instructions first and I totally agree-read them a couple times and familiarize yourself with the boards
