carl,you will proberly find that the wheels you have bought come with an offset something like et35 to et38,which is spot on for you car dude

with regards to rubbing,its a bit and hit and miss,some cars rub some dont.
your springs and shocks are proberly old now which dont help
so as peeps have said on 2 different posts no,either get them rolled or get the rubber mallet out and tap them up a bit

ONE OTHER THING NOW I THINK OF IT,PHONE THE SHOP UP AND DOUBLE CHECK THEY AINT GAVE YOU PEUGEOT OFFSET,WHICH WITH BE ABOUT ET16 TO 16 COS THEY HAVE THE SAME PCD
