faststiwagon

i have a 2002 wrx wagon and am doing the full 2006 sti drivetrain swap in afew days. am i to believe that i can use my wrx brakes in the front and then have to use the sti brakes in the back if im using the 2006 sti hubs? also with using the 2006 sti hubs will the abs system hookup or is there a way to mate the two together that will work? thanks
