Looks like you have too much rear sag, a good starting point would be 35mm (with rider, feet on pegs and someone holding bike) and go harder or softer as required.
I would also soften the front to 35-40mm with rider as above.
Adjusting the damping is a bit harder without knowing your riding style or the roads around you. My advice is to find a good suspension specialist close by and pay the £40-50 to set it up for you.
