welcome aboard. Another experienced rider. Time to hit the mountains and see just how much of an upgrade you really got. As far as being vertically challenged, there have been some riders who get thicker soles on their boots. That seems the safest.
I've seen lowering kits for other bikes and shorter shocks, but not for this bike.
You'll have to be careful parking/moving slow around gravel and Harleys (oil on the ground) hahahahaha
