Here is a thread asking this question last week.

Use 5wt oil. Modern forks shouldn't be tuned with oil viscosity. They all work correctly with 5wt oil.
Unless you have some complaint your trying to address, the stock oil height is fine.
Before making any changes from stock you need to evaluate what you have, identify the characteristics you would like to change and then ask specific questions about how to address specific problems. What I like in suspension action may not be what you like. I weight 60 lbs more than you so my settings are going to be different. But, if you have a specific condition you would like to changes, we could point you in the right direction. But, suspension tuning is always going to require testing and trying different settings until you arrive at the ones that best suit you, you track/roads and your riding style.
I just spent last Saturday working on the suspension of my dirt bike. I had a specific condition I had identified (bike wanted to follow the contour of whoops and didn't want to get on top and stay on top of them). I exchanged some emails with the guy that re-valved my suspension, got some suggestions of things to try and went out and tested them for about 3 hours. Ride the loop I like to use for testing, make a change, ride it again, note the difference, make another change, ride it again, not the difference, repeat until you get the best settings. Made big improvement in the condition I was trying to address without doing to much negative to the other aspects of the bikes handling. But, after 3 hours, I'm still not totally satisfied with it. I'm going to exchange some more emails with my runner and then go back out next weekend and work on it some more.
Point being, unless you have some specific condition your trying to address, it's just turning clickers for some blind luck setting you find better.
