Too much toe in will cause the outside edge of a tire to wear abnormally fast. Too much positive camber will cause an area just inbound of the outside(usually the second rib) to wear abnormally fast.
I don't recall alignment adjustments for your car, but many FWD cars have no built in adjusters. For some of these cars there are shims made in the aftermarket to correct alignment. Before there were shims, we used to use a porta-power or hydraulic bottle jack to "coax" cars into alignment.
1/32 may not sound like much but it's probably about 10% of the usable tread!
My personal reccommendation is to get your car's alignment checked at either an alignment shop or a tire dealer. The guys working at these places usually know alot more about alignment wear than guys at a dealership--they're probably less expensive too.
