What did Shelby touch while in the office. And where are these items located?

I can't remember exactly everything off the top of my head everything, but often missed points are:
 
-The windowsill that Shelby just touched in the scene right before covering up evidence
-The door
- Both phones.
- Magnifying glass
- Both shot glasses and the scotch
- The ballerina
 
They're the major ones off the top of my head. There's a few random spots in the place that you have to cover up for though (for example, the random glass top to one of the displays), so comb the office before leaving. You have tons of time.
