My goal would be to utilize sub placement and room treatment first before applying any eq.

You’re doing treatments in your office? Impressive.

Bass traps are the treatment usually used for low frequencies (although as brucek noted, their “reach” only extends so far), but I doubt you’ll want any in your office! Their primary function is to reduce extended signal decay times (aka “ringing,” for some inexplicable reason) and reduce the gap between the peaks and valleys. Judging from your graph, you don’t really have any peaks or valleys significant enough to warrant traps, so unless you want to reduce decay times there’s no reason for them.

Based on the graph would placement / treatment work?

Sure, placement often works, but you won’t know how well without graphs from the various locations.

What problems exist here in your opinion and what would you do to correct? I know it's a subjective question with only the graph but I want to make sure I've got the basics down using REW before moving on.

Keep in mind that a computer sub is low powered with a light duty driver, so you can’t get too aggressive with equalization. Most likely you won’t be able to turn it up as loud as you can now after equalizing.

That said, I picked up a car audio Alpine 7400 parametric EQ off eBay for my office system. Unlike the BFD, the Alpine small enough to sit on top of the sub – i.e., not take up a lot of real estate. It’ll only do a couple of bass filters, which is fine for a non-critical situation like this. A single broad filter would help bring the above 65-Hz area down to the below-65 Hz region.
