Using the best filters, fluids and parts you can will help.
Using top tier fuel should be considered mandatory. High octane highly recommended.
Use the manuals recommendations but you should be changing the brake fluid every 2yrs/60k in my opinion, and I wouldn't let the trans fluid go beyond 100k in an auto. I think the manuals severe duty recommendations are overkill for a highway commuter, as this should have you changing trans fluid every year.(if you're okay with this expense, it's obviously not detrimental, but a trans fluid exchange is typically the most expensive bit of maintenance on this car and doing one a year at 45k is definitely overkill)
It's hard to beat Mobil 1 or Pennzoil Platinum for a Walmart/parts store oil change. Consider Amsoil if comfortable buying online(or if you have a local distributor) and getting used oil analysis done to keep track of fuel dilution and make sure running 12-15000 mile or longer oil change intervals. I'd stick to 7500 miles max on the UPF64R ACDelco filter and change it out during the course of any extended OCI routine you adopt. It's a good filter, it's less than $5 online, and there is still confusion/unclarity regarding whether or not any of the aftermarket filters available actually meet all of the filters specs.
