Personally, I feel like the stock springs are for 98 lb Japanese guys. I would pre-load them a lot and raise the forks in the clamps about 10mm.
The rear doesn't have a pre-load adjustment (quoting GW) However it has a ride height adjustment.
I would be looking at Sonic Springs for a new set of fork springs.
