Lynn, I've fashioned a number of these for various planes, and I don't think you need a precise temperature. What is needed is a sensitive touch, and discriminating use of the heat gun.
This is certainly the time of year to do this. Any job with plexi (windows, etc) is a lot better in the summer! This stuff gets brittle to work with in the winter! I would save this job for last, using the outside re-enforcer or bezel as a pattern for the piece of plexi. I would make the screw holes in advance, and without the re-enforcement or bezel attach just the bottom screws. I like to use a soldering iron with a slender, conical tip to make pilot holes for the screws. Then using the heat gun very carefully, I would slowly bend the plexi to fit the leading edge, being careful to neither use too much heat, or bend it too fast. You just have to feel it. You only need heat on the place that is actually bending. Once you get your shape, put the screws in and let it cool. When it does it will retain the shape of the leading edge. Hope this works for you!
