    Would you place rock wool over the entire ceiling(including joists) or just in between the joist spacings?

    Lastly, windows. What needs to be done with those?
    The job will only be as good as it's weakest link. So double drywall and insulation is wasted if you have windows untreated.

    Same with your door. If it's a hollow core door, it's going to resonate and transmit sound structurally.

    Same with electrical outlets. Sound flanks and will escape. You will want to make the room as airtight as you can.

    Best case scenario for windows is to build over them. Otherwise, removable panels that fit snugly could work, if you can find a way to make it airtight.

    You don't have to do this all at once, FYI.
    Drywall is relatively inexpensive, so doing the double layer of drywall to start out would be a good starting point. If you can't afford the compressed fibreglass or rockwool insulation behind the drywall, you might try a thicker ( R-25) layer of "pink" fibreglass insulation.

    Only between the joists.

    If you want to improve TL through the ceiling, place one or two layers of drywall up between the joists against the sub-floor before you put in the fiberglass.

    You have several options; 1. block them up completely. 2. add a thick 'fixed' panel to the window opening and seal well. 3. open the windows for additional bass trapping. - just kidding. haha. Scratch #3. (Ever wonder who writes those stupid multiple choice questions on tests??)

    Also, FYI, the good old pink fluffy stuff is actually better in the walls than OC 703 or any compressed stuff. It's function is quite different inside the wall cavity.
