A few things.
1) Typically, you'll want your monitors at ear level, and they should be pointed at your ears.
2) They should form an isosceles triangle with your listening position.
3) If possible, have your listening position and studio desk in the center of one wall. This will give you the most balanced sound results.
4) Isolate your studio monitors from the surface they are sitting on with some Auralex mopads or similar.
5) I'd recommend getting Owens Corning 703 panels to treat the first reflections in your work space.
5) Then, treat the corners of your rooms with dense OC703 panels to absorb the bass.
