Aloha Red Fortune,
In the example of the relationship star in the bedroom that spills over to the bedroom - activate it in the bedroom, and remember to keep the bathroom's toilette lid down, and drains closed when not in use.
I'm not real clear on your front door question, so I'll give more of a comment than answer and you can redirect or clarify your question from there.
Your front door has a facing direction (what you read standing, facing out from the threshold for your 20-year period calculation).
Your front door also falls into a section of your floor plan's pie or 9-grid chart. It can be a North facing door, but in the East section of your chart. If that East section has a disaster star on it and both the front door and the garage are in it, place the cure for that star in the area of the front door. The garage doesn't reduce the impact of the negative star like a bathroom would, regardless, cure/activate your front door.
Much Love,
Shawn
