Hello Geo,
You have some brilliant photographs. I have no pictures at all of my Scottish ancestry, so I'm quite jealous.
The picture of "The Lodge Blair House" has frustrated me. I'm sure I recognise the cleanly cut stone and distinctive shape of the door -- but I might very well not. It looks like the sort of house which belongs on Perth Road, Newton Street, or Keay Street -- that sort of area. I will stroll that way in the near future for you and see if I can spot the house.
I believe the primary school is Hill Primary School (Google street view:
http://tinyurl.com/5uxuqd2). Not only because of the location, but also because of the stonework, the decorative stonework around the windows, and the width between the window "columns". If they took photographs then in the same way they did when I was at school (front row sitting on the ground, second sitting on benches, third standing on ground, fourth standing on benches) then I'd estimate the windows to be about the same height too. The school was closed last year and now the gates are locked securely, so I couldn't get in to see if the wall on the left of the photograph still remains. In contrast to the grills I could see and which are in the street view, the grill in the photograph is also above the sill of the window, but the design of the grill is the same.
I've just used street view to look at the back of the school (here:

From what I can tell there is two windows of three columns at the back of the school, so I would think that is where your father was standing for his photograph. (Also notice the rounded top of the wall in your photograph, and the rounded top of the walls in the street view.)
More good news: the building which was your grandfather's smiddy still exists (street view:
http://tinyurl.com/6cpg5hp). Look at the roof windows (two sets of three windows, now gone since the street view was taken), the size of the door, the gap between the window and the door, and the same narrow gap between the window and the roof, and the door and the roof. Unfortunately the gates to the building are always shut so there's no chance of a better picture. But I will look at the library blacksmith pictures I previously mentioned, and see if there are any similarities.
The church may be the church on James Street which is next to Hill Primary (you can see it in the background from the school street view). But there is also another church very nearby at the bottom of Kirk Wynd, and another on George Street (North/East end).
