Insulation help for my garage with pics

hers would i would do i used to be a licensed carpenter-

1-take the stuff down that is up there

2-install a few more 2bys from the angled part of the truss(THESE ARE CALLED THE RISE PORTIONS) down to the lower cord of the truss(the horizontal pieces where the stuff sits
3-lay down some plywood of chip board to lay your stuff on incase you havent already by doing this its spreads the load of weight that is up there across many trusses
4-install vented soffit outside under the eves so you can get airflow upinto the roof so it doesnt cause any rot or mold
5-while the stuff is down install the silverboard on the angled part of the truss across the trusses like the plywood on the roof
6-this will insulate in 2 ways the boards holding your stuff will help keep the heat closer to the ground for now and the silverboard keep it from escaping:cheese:
