I think you did great!
The only thing I would have done differently is to: "keep the lights turned OFF!"
Turning the lights on "INSIDE" your house does a few things you may NOT want to happen:
1. It gives the advantage to a potential BG by letting them know where you are located inside your home.
2. It can also allow your movement to be illuminated. (This can open you and your family members up for getting SHOT from the outside.)
3. Having an inside light "on", detrimentally affects your night vision and creates a reflextion in the window that can make it more difficult to see someone "clearly" who is outside your home in the dark.
May I suggest taking advantage of the knowledge you have about your home. Then move through the house in the dark to find the best place to observe and call 911.
If this is not possible, then I suggest turning on "OUTSIDE" lights to illuminate the BGs while you and your wife/family remain in the concealment that your "dark" home affords you. You also need to have a place of "cover" from which you can mount a defense should it be necessary.
Just the same, I still think you did very well; and I certainly am glad you and your wife are OK.
