I don't know if it works for all programs, but if you position the program to the size and location you want it, hold down ctrl and push the exit button. Then the next time you run the program it should re open it in the same spot and teh same size as last time.
I use that when ever firefox decides it wants to open on the right monitor, I just move it to my left monitor, and resize it so that it takes up all of the screen and then I close it while holding ctrl.
One side note: I am almost positive that you can't have the window maximized.
