I'm not sure you should adjust the x or y of your rectangle. If you ever deal with paths or polygons, this method would get far more complicated.
In the second part of your email, it sounds like you're having trouble managing transforms when translating/scaling/rotating any amount of times in any order. I found this a real pain in the neck. With my transforms, I applied (in order) translate, then scale, then rotate (I didn't mess with skew and shear). If I wanted to change say, the translate value, I would UNDO the rotate, then UNDO the scale, apply the translation, then REDO the scale and REDO the rotate. I have a utility class that can help immensely with this. I'll attach it to this message. If that fails, let me know and I can send it directly to you.
