Default Newbie with ANOTHER MPG question

Hi all,
I've wanted a truck for a while now and FINALLY got a Ram 1500 Lonestar Crew Cab with a 5.7L HEMI. I absolutely love it, and I'm having 0 buyer regrets!

But of course, there is the never-ending curiousity about better gas mileage. I was determining whether or not to get a bed cover, so I did some research. For every article I find that says bed covers improve mpg, I can find an article that says it's a myth (most articles that say covers improve MPG are on sites trying to SELL bed covers).

I've read more into various forums and, aside from bed covers, I see 3 things continue to pop up.
1) Cold air intake
2) Computer programmer
3) Free flow exhaust system

Although, after looking into these I've found many disagree with them as well.

I don't know enough about engines to make a best-guess decision for myself. So, any help?? ASIDE from the obvious - slowing down, light foot on the gas, using cruise control....what are some options? Are there any options worth the money it will cost?

Yes, I know I bought a HEMI, and really - I'm not complaining at all. I love my truck and will probably never drive anything else. I just thought if there's room for improvement, why not do it now while it's still new???

Any...ANY...CONSTRUCTIVE suggestions/help would be GREATLY appreciated!

Should post this in the MPG section where they have the state of mind to improve gas not haul ass.

I have a bed cover.. which I installed for personal purposes ( have a tool box in it).. and is just great for keeping things protected back there.

I installed an S&B Cold Air Intake about 2 weeks ago.. and I have noticed an increase in mileage since install. I also installed a flowmaster super 44 muffler onto the original exhaust pipes.. but that was more for sounds preference.. The CAI offers a nice sound too.
This tank that I ran down to 1/8th remaining before filling today.. I achieved over 50-60km more then I have ever accomplished on running my truck down to fumes since I got my 08 in early October. Mostly a combo of city 70%, HWY 30%. Weather for the past week has also been in the negatives for the most part.. So can't say warm weather helped improve it.
