Can I use REW to help place my main speakers? Would I need to upgrade from the Radio Shack Meter to Behringer ECM8000 Measurement Microphone?

How is the Behringer mic hooked up?

I have experimented with the speakers and not heard a huge difference in sound but it can be hard to pick up changes. I use my dedicated HT for 95% movies.

For what it is worth here is a photo of the front speakers you get an idea of the placement. I have moved the subs closer to the center channel due to REW readings. The Subs are HSU ULS-15's the LCR are Paradigm LCR 450's.

Any help is appreciated.

What do you mean by "place" the speakers?

Yes.

The RS meter is only accurate to about 3KHz. For full range the ECM8000 (plus preamp) or Galaxy CM-140 is a good choice (and well worth the investment).

Thanks for the compliments on the room, I do woodworking for a living so it was all in a days work for me.

What I mean by place is locate and point. I have read much more about deep bass but I assume you want to limit big peaks and valleys in the higher frequencies also?

I wouldn't worry about the so called "deep bass" as your mains should not be going below 60Hz anyhow let the subs do the work. Have you tried moving your subs to the outside corners? I think that just by looks your mains are fine just where they are.

I also agree, very nice work on the room

I have measured and moved the subs and they measure and sound fine.

I am wondering if I can improve the sound by adjusting the placement of the front speakers.

Well, judging from the picture, you don't appear to have much "wriggle room" in the placement department.

Still, it never hurts to experiment. As brucek mentioned, the RS meter is only accurate up to about 3 kHz. Fortunately, the rule of thumb is that the room's effect on a speaker's response is primarily below 1 kHz, so the RS Meter should do fine for what you want.

Given the close proximity to your seating position I would not think much more can be done. I think maybe moving them in to wards the screen maybe a foot would help with the imaging for the person sitting in the center of the front couch. Can you push the front seats back a bit?

I had the basement finished when we built the house. The HT was just dry walled no moldings or paint. With all that was going on with my business and building the house I did not have the time to do the kind of research needed before building a HT. I made the room to short, bummer. The room is TIGHT.
There is no room to move the chairs. The reality is that very seldom does someone sit in the front. If they do its a kid or we have company. Truthfully the near field position of the speakers dos not sound bad.

You stated in your first post that you like how they sound "I have experimented with the speakers and not heard a huge difference in sound but it can be hard to pick up changes" I would not worry about it and just enjoy it. I only wish my room looked as nice as yours.
You may want to raise the front left and right speakers maybe another foot so that they fire more over the front row if that is where you sit most of the time. Your center looks good.
