Depends to a large degree on variables such as weight, winds etc, but generally I would be flap 1 at 180, and then select flap 2 when asked to reduce to 160. If this is not enough then either flap 3 or a bit of speed brake to bring it back to 160....
At somewhere between 4 and 5 miles I'd then go for gear down, managed speed to start reducing to Vapp, again depending on wind, aircraft type, Vapp and landing flap.
