Duro tires are a new name for an old brand (and I can't think of the orginal company).. Nothing wrong with them, but they're not expensive..
As far as pressures, if I'm riding mostly roads, I run road pressures... 33 Front and 35 Rear.. If I'm riding off road, I air them down to 18 front and rear, and as soon as I'm back to regular road riding, I air them back up as soon as possible.
One trick that many do with a wandering front end is raise the tubes in the tripleclamps.. In other words, bring the tops of the fork tubes up above the top clamp..
I'd try .300" to start out with.. You'll notice a difference right away, with the front end feeling more planted, but you will also lose a bit of clearance when doing this.
Also, give the bike a good once over as Don mentioned.. If nothing else, you'll learn about the bike.
Remember, take care of the simple and cheap things first, before even considering changing out to aftermarket or non-original forks.. I'll bet you find what you're after for zero cost..
