0.95 springs and 10w fork oil are what you need. I would do that first before trying anything else, if you later decide valving changes are needed you'll still want to have the right spring rate in there.
Either Race-Tech or Sonic springs are fine, both are quality straight-rate springs.
I used to own Sonic Springs so I'm a little partial to them, and the current owner is a very knowledgeable guy, so that would be my vote.
