ajlafleche - Glue question

I use a drafting pen I found at a yard sale. You can adjust the amount of glue with a screw that opens and closes the tip. It's easy yo clean, applies an exacty amount and never wears out. If you can't find one of these (I don;t know how much one cost new), as Gino says, use a fine brush. The included applicator is too thick.

Depends on the seam. Generally a smaller brush is better than the applicator brushes they put in most liquid glue jars. You align the parts and place the glue at the seam, the glue will wick along the seam by capillary action.

It should come with a brush attached to the cap of the bottle. Any fine brush will work though.
