@006 E250 service
Y Of course only if you do not want to risk ruining your driveway with oil

Intake an fuel system? WTF...pick up an air filter at NAPA and a can of techron concentrate. Replace the air filter (really easy) and add the additive to the fuel tank as directed on the can. That's all there is to it.
For the power steering:
Grab a quart of MERCON (V) ATF and a syringe from the hardware store, open
the reservoir for Power Steering fluid and pull out the old fluid, dumping it in another container. Should be around 100 ml. Replace with same amount of new fluid in the reservoir, put on lid, drive a mile. Repeat until you took out a quart. You're done when the bottle of new fluid is empty. Not totally effective, but a cheap way to keep your power steering alive without having to pull any hose or risking leaks.
saved you $100s...i
There are intervals at which fluids should be changed as per the Factory Service Manual (FSM) You'll also find this info in the vehicle's owners manual (if you have one?)
At 80K, that's a service point, and the dealer has giving you the "list" from that point. Do you follow that list? That's up to you, most people do not follow the "written list" to the letter.
From what you wrote, if you can do some of the work yourself, that's great, most of us on here do most, if not all our own work

If not, find a good local corner garage, with a ASE certified mechanic, and keep away from the "All Car Care Centers" their worst than the dealers for up-sales and throwing parts at the thing until your wallet goes bust

For your 2006, I take it, you just got it and don't know who did what and when??
First, Do NOT use MERCON (V) ATF for the power steering fluid change, from '05+ (or earlier) the spec's call for Synthetic Power Steering Fluid, in fact, I've never used ATF for the power steering, always specific power steering fluid. ATF will burn out the seals for the power steering, and cause leaking.
This is not really needed to be done, just check that the fluid is at the proper level, and top of with the correct fluid.
In your case, I would do the coolant flush, again, there are special steps to do this, not just drop the old and replace, it's almost a power type flush for the coolant. Coolant that now 11 year old, time to replace.
Tranny flush, that's up to you, but again, there are special steps to do this correctly.
Fuel system cleaning? Couple cans of Lucite in the fuel tank will do this.
Overall.........at 80K, I would do coolant flush, check all fluids, new air filter, and go as far as replacing the plugs and boots/springs. Check the COP's and do a scan for codes. And any PM issues.

Spec's changed from some year models, and with the wrong fluid, it could cause problems.
