Ok, lets start with the event type.
You set your event to autorun, that event will take priority over everything else, basicly freezing your control.
You will need to properly end that event, so you get the control back.
Next the starting position, yes you need to set that on your map, but you need to remove the character graphic in the database, sou you don't actually see your player character.
Then yea, 2 events for your 2 persons.
So lets go for your "cut scene" event.
You can do that in one of those 2 events that are your persons, or in a new one, doesn't really matter.
Lets go with the one you started. Autorun is ok, but the first bubble your showing should be on top of the event you want it on, since you have it shwoing above your player, which shouldn't be right.
Also, you shouldn't do the movement how you did it so far, but instead do it with movement commands right in the event, where you have your text.
So put all the movement for both chars in there, before the text you want to display.
Then after you said everything you wanted to, you need to end that autorun event.
Use a self switch, should be on commands page 1, "control self switch", you should be able to find it.
Turn self switch A ON there.
Then you need to create a 2nd event page (where it says "create new event page" on the top), make it on action button as the trigger and check self switch A in the options on the left.
That way your cutscene pulls through and turns the event into a blank one at the end, gicing you control over you character again.
After your done, you need to change the graphic of your player back to what it should be ("change actor graphic" somewhere in the commands) and then teleport the player onto the next map.
