Finally! I've set the target level, before measuring, and came up with the following graph.

From what REW is saying, I need to input cuts at 37 and 45, right? Here's the graph:

I'm reading the BFD manual/help files and see that I need to know how wide to make the filter. According to REW I need to cut 37.2Hz back 6.3db, and also cut 45.5 back 4.0db, but how do I know how wide to make it?
Much thanks on the help--I'm thrilled to be this close!
Also, what to do about the 70Hz dip?
The Shack rocks...
