I'm flying FS2004 for some time now and things are going better and better. But as of today I can only perform ILS landings

since I never managed to line up my plane straight with the runway when doing a visual approach. I must say that I also fly on autopilot (thus resetting the HDG button) to line up with the runway. Since I fly JAF's 738 to leisure destinations most of the time, I often have to land at airports without ILS, but by not managing to put my plane down on the proper way, that is a problem. I do manage to land them, but I wouldn't want to be a passenger on such flight

Now my first question: do I better fly manual to line up the runway (having a more manual control over the plane) and is there a visual trick to line up perfectly with the runway?
My second question: when I request a pushback the plane never turns at the right point (following the taxilines). It either turns way too early or not at all. With both ways I have to correct it myself and it lacks realism. I have to immediately push '2' after the 'SHIFT+P', resulting in turning to early, or it doesn't turn at all.
My third question: does anyone know where I can find the Brussels Airlines A330 repaint for Simmer's Sky A330-300? I haven't found it yet.
Thanks
