If your going to remove the caliper and rotor, yo'll need a 14mm socket and a 6" extension for the rear caliper bolts and two 8mmx1.25 bolts to remove the rotor from the hub.
BTW the Hub is the bearing assembly, just in case you wanted to know.
The front calipers are 17mm sockets.
Use anti-seize compound on all the nuts and bolts, even lug nuts when you re-assemble.
Oh I see yours is a 2.5i but the basic stuff should be the same.
