Use the o-rings not the sleeves, yes you have to dremel off a litttle bit on the front set. I have the exact same setup for about a year I haven't encountered any problems. Before you start working on it...measure out the all four wheels between the fenders and the tires that'll make it easier to align. DO NOT drop it more than 1.5 inches' than stock...the shocks can't handle that much of a drop.
