I wouldn't install face dots before radiusing the board. As mostly the dot thickness is only 2mm, the further away you install them from the centerline, the deeper they will have to be installed, and calculating that could be hit or miss. Since you have a brad point drill, you could drill the dots after the board has been radiused. After glueing and curing, you could get them almost flush with a fine file, and then radius sand a bit more to get everything perfectly level.
EDIT : I think it would be a good idea to drill perpendicular to the radius surface for dot installation. It won't make any difference to the appearance, But it just means the dot can be installed slightly deeper. With a 16"radius board actually it won't make a difference.
