Insulation help for my garage with pics

I would put Stro vents in every 3rd truss. Use bat insulation to fill in the gap area left over from the vents.Put R13 in the ceiling Poly it then add what ever to the underside. R13 isnt thick so it shouldnt be sticing up causing problems with stuff in the rafters....Remember you need air flow and dont put any insulation in tight...........I did this for a living along time ago...........Door looks good......Edd BTW.........If the bat insulation bugs you , glove mask and then a cool shower for a bit then to hot.......Keep the pours open to get rid of the insulation........Hot water opens them......JM2C
