I havent quite figured out the chipping system quite yet, and its frustrating man, i know it...generally, your going to be looking at about half the power of the club....so if you chip says it will go 20 yards...expect only about 10...although that doesnt take the run into account.
As for puttings, for a hole that lies higher on the green, go about 1 foot past for every inch above....so, if the hole is 20 feet away and 5 inches up, shoot for 25 ft. For a hole thats below you, i usually drop back about 50% or so. The slant left to right on the green is the worst part of my game, usually I just wing that, but its one of those things you just need to keep doing until you get it.
hope that helps a little at least
