Mufflers are just personal preference. Flowmasters are of course the most popular now for some reason, but to each their own on that. I'd really reconsider the 3" exhaust, the truck would run better with a 2.5" pipe. You have to make sure to create the proper back pressure and not let it be so open. Others will chime in that know a ton more than I do, hopefully.

As far as gas tanks, you have a few options. You can put the other saddle tank on and wire it up with a switch like the factory twin tank setup, giving you two 16 gallon tanks. Or your other option is putting a suburban/blazer gas tank between the rear frame rails. This would give you the option of a single 25 or 31 gallon tank. Your short bed can not use the big 40 gallon suburban tank though, too long.

Hope any of that helps you, and thank you for your service in the USMC, and be careful so you can come home and finish the truck!
