When I started with barre chords, my teacher always told me to first place my index finger, and then when every note sounded ok, I had to place my other fingers. When the chord sounded good, I had to move it to a higher and lower frets.

If you are well trained in the 'normal barre' chords, you can always go further with more jazzy chords: the 7,9,13 chords. These are very good to exercise your hand. Succes!
