I am helping my sister add insulation to her attic space, she has just purchased a 100= yr old house and wants to leave the beams exposed, sheet rock and insulate in between the beams. She purchased rigid foam board insulation at the advice of a home inspector, trying to get an idea on how to best install the insulation so that she can sheet rock over it, yet between the beams

If i were her, i would paint the underside of the roof with a heat reflective paint (brush,roller,or spray)and leave the insulation alone.You can then paint the heat shield with any color of paint once it is dry.Seems like you could have condensation/ventilation problems doing it the other way.Just do a search on the web for "heat reflecting paint" and there are solvent-free products out there for about 150.00 for a five gallon pail.At least check it out.

Two solutions: in the increasing levels of difficulty/expense
One: use a contact adhesive ( you would get at any hardware/DIY store.Cut the insulation sheets using a hack-saw blade( wear goggles and cover your face with a filter mask!). Apply adhesive on the cut sheets and apply on the area you want to.
Two: call a Polyurethane spray contractor( he will bring in his own equipment and a two componenet liquid that will make the Polyurethane foam insulation in-situ). He will mask the area where you dont want the insulation and spray a uniform coat on the desired area.
