After you have enabled the palettes you need, you can move them around and dock them to other palettes to build the workspace you prefer.
Click and drag on the title bar and place it over another palette to get the palette control tool.
Mouse over the arrows to see a shaded view of where the palette you are moving is going to be docked. Let go when you have it where you want it.
You can then resize the palettes by clicking the edges (top, bottom, left, right) and drag the border to resize the palette to view all of the conents.
