Hi and welcome.
I've got 5PW forks in mine but they have K-tech internals so my settings won't be of any use.
You don't say what weight you are but I'd always start any suspension set-up work by measuring and adjusting the sag. If it's the springs that are too soft, you'll find out this way and will know for sure that new springs are required.
Assuming you can get the sag right with the springs you have, I'd start the process of damping adjustment by turning the compression dampers a half turn out from max and do the same with the rebound screws, too.
IIRC, the adjustment range for compression is from 0 (max) to 13 clicks out. Rebound screws are similar. Standard settings are something like 7 clicks out (comp) and 5-6 clicks for rebound.
