The wrapped present sits on the coffee table and Joy sits staring at it.
Could I replace the first "sits" with "is placed" or is that an action?
Yes,it's an action, so you are changing the meaning a little bit.

Depending on the shape of the present, you can use 'stands' or 'lies' (on the coffee table).
