I will have to check my manual, but I really wouldnt think the steering head bearings need replacement that often, unless you land lots of hard wheelies! Grease and adjust at the most.
You can run bit lower pressures for more grip and a softer ride too, unless you are 2-up or carrying a heavy load. I tend to stick around 32 front, 34-36 rear, and I know lots of guys go lower for more grip. I tend to like my setting for a compromise between max grip and max carrying capacity.
You'll have to play with that Ohlins rear shock some, figure out how to dial that puppy for your weight and style and I bet you will be much happier. Hopefully someone who has one can chime in with advice on that!
