I would just place a cure for the disaster star.
After all, Space Feng Shui first. If I remember correctly you can get the most benefits from Time Feng Shui if you have done all space Feng Shui activations; i.e. activate the your (and husband's) best directions in your bedroom, living room and office as explained on Level 1. Look up the specific activations for you and your husband in the manual. I would only place the activations for this area as described in the level 1 manual and only those for you and your husband for personal space feng shui, and the activations for general space feng shui.
Personally, I wouldn't even bother about your garage unless there is good star on it ...
