Congrats! Are you using instrumentation yet? I'm guessing no based on your "by ear" comment. I did the same for a bit, but saw HUGE gains once I got my MPGuino. Since your truck is new, get a SGII - it will pay itself off fast.
Read around here more on the pressure thing; most of us split the difference - the manufacturer tire psi is a minimum for safety. I fill to a bit above that on all our cars - sometimes you go a few weeks or a month without checking. Going from 38 psi to 32 is no big deal for FE or safety. Going from 33 to 27 is not as safe (although not awful) and WILL hurt FE.
