As cheermom1 alluded to, the smell of smoke is easy to debunk. This is what TAPS would say, "During renovations, the smell of smoke can be released from walls and other surfaces as they are disturbed. Not saying this is exactly what you experienced, but it's another possible explanation."
As for the shadow, they're pretty good about debunking those.
In conclusion, they'll tell you you have nothing to fear. If there are any spirits there, they are people who loved the house just as much as you do.
Now I just wish they would debunk the loud knock we heard above our bed, quite distinctly inside and on the drywall, hehe.
