Genlemen. RTFQ!
Get out a picture of your PFD and follow me here. Everything you need is there. You need a pitch target and a heading target.
For a 30 Flap landing your pitch target is about 2 deg. Place the small square on the a/c symbol just under the 2 1/2 line on your ADI. Make adjustments as required but always come back there. For a 20 Flap approach your pitch target is 2 1/2 deg.
Now look at the bottom of your PFD. The half compas display there has a white track line. This is your track over the ground. On your PFD, set runway heading. (It's not going to slew there automatically unless one of you has your FD on and arms the Approach, but we're talking raw data here.) Now as you steer, your heading target is your heading bug. Steer to lay the white track line over the heading bug. Once you're squared up your corrections should be very small. Keep the track line within or very close to the heading bug.
Voila. Send only happy thoughts.
