The dots are a continuation of the glidepath to the runway. This procedure is designed to follow the CDFA approach concept. Constant Descent Final Approach.
Above the profile view is a table showing DME distances and altitudes. You can see it in the attached image above. The idea is to start the descent at the 9.0 DME inboard towards the VOR and to try and hit the altitudes on the table for each 1NM. If you can do this, you will be on a constant descent to the runway which is a 3.30° glidepath.
The missed approach arrow is before the MAP because if you continue at MDA after that point, you may not be in a position to land within the touchdown zone on the runway. This is part of the CDFA concept.
I can't tell from the attached picture above but the minimums may have (MDA) or (DA) listed. If it is a MDA (which it probably is) increase the altitude listed by at least 50' to make it a derived decision altitude (DDA). This allows you to descend on a constant descent and if you don't have the airport/runway in sight at the DDA, to execute the missed approach without going below MDA.
