I don't know if the ecoboost is much different than my 5.0, but oil changes are are quick and easy. I changed my plugs at 100,000 miles and they still looked good enough that I could have just tightened up the gaps a touch, and re-used them.
I did take it in to put on the new serpentine belts, because the front one was a pain to get to, although it also looked like it could run another 100,000.
As far as fuel-injector cleaner goes, the only thing you will hurt by using it is your wallet. Let's do the math, a 36 gallon tank takes 2 cans of Berryman B12, @$3.17 per can at Walmart, which would add $0.17 per gallon onto your fuel cost.
It is beneficial to use it once in a while though, as an aggressive cleaner will keep everything whistle clean.
If you do decide to start modding / improving your truck, this is the place to be - lots of good advice and experience here.

Yes, they are completely different when it comes to spark plugs and injection cleaners.
The 5.0 does great with plugs where as the 3.5 has been known to go through them rather quickly. Also (correct me if I am wrong) but the 5.0 is multi-port fuel injected and not direct injected like the 3.5l so cleaners actually are sprayed on the valves. They also don't have to worry about over heating a turbo with the cleaner, which, to me is the biggest issue with injection cleaner.

Got the new plugs in.. all original plugs were .050 and over. Got it all in at .030 and started it up to receive the same rough idle it had... 2 min into start up it just smoothed out and was like butter.. did some reading to find out gapping the plugs lower can cause a rougher cold idle but smooths out as it warms up.. apparently mine all under that category. will drive soon and see how it is.

The first time the computer needs a couple of minutes to readjust all of the settings from the previous plugs being .50 instead of .30. It should be good from here on out.

Yeah, seems great now! More responsive. The thing is so smooth at stop lights I can barely tell its even running at all. Now I just have to resolve that pesky thud stopping and starting.. Super annoying. If I can fix that I will be extremely happy with the truck.

If you have the open differential, the synthetic fluid doesn't require changing too often - I'd go 80k - 100k miles. If your truck has a trac loc, I'd change the fluid and anti-slip additive every 40k.On mine, with the TrueTrac I change it every 30k. Since cleaning up the surfaces is a pain I put on a cover with a drain plug.On your front 'punkin, a person puts so few miles on them that you'll never wear out the fluid with the factory open differential. So when you service the rear, just screw out the fill plug, and make sure you didn't leak any out and you should be good to go.
