The best way to scale to the size you want is to look at the bounding box 
values of your graphic:
	%%BoundingBox:5 40 715 530

These represent the lower left and upper right coordinates of your graphic.
This defines a rectange that is 710 x 490 points (where a point is 1/72").
You'll want to scale this down to a rectangle of 216 x 144 points (3" x 2").

Stick the following code at the top of the file:

	/MyScale { 216 710 div 144 490 div scale } bind def

This will scale non-uniformly but ensures that the graphic is exactly 
2" x 3".

If you want to scale uniformly in the X direction:

	/MyScale { 216 710 div dup scale } bind def

If you want to scale uniformly in the Y direction:

	/MyScale { 144 490 div dup scale } bind def

You'll probably also want to translate the picture around on the page:

	X Y translate			% Position on the page
	MyScale				% Scale to desired size
	-5 -40 translate		% Translate pic to lower left corner

Where X and Y are expressed in 1/72 of an inch.  If you want the resulting
picture to be 1 inch from the left hand edge of the page and 2 inches
from the bottom, then X = 72 and Y = 144.

Hope this helps,
