What is the right maintenance on a 2011 galant se?

[2011GALANTse]

Okay i bought the car May 1st of 2011, Since May i have put on 20000k miles all highway miles from my drive, back and forth to work is 100 miles. Since the start of owning the car I have gotten a oil change every 2500-3000k miles I also have got the tires rotated and balanced 3 times...I would like to know now what do i need to do at 20,000 milestone?
I also would like to say when i brake i feel a little stutter when im braking at the speed of 60 miles per hour nothing too crazy but i feel it..I also took a look at the brakes and they look pretty beefy..Any information will be very helpfull.

20,000 maintainence:

I'd replace the air filter, oil change (if you're due) fuel filter.

The brakes, you may have warped rotors. Did you have the brakes serviced/replaced at all in your ownership? If so, did the shop replace or cut the rotors? "pad slaps" are a huge no-no, since it improperly beds in the brake pads and causes bad rotor and pad wear, and bad pedal feel.

You didn't answer about your brakes though.

Nothing has been replaced by the dealership, everything is original...

Your air filter is super easy to check, and $10 at a local autozone for a new filter.

Ask for a labor history for all the work done to the Galant from the dealer. Depending on warranties, sometimes "scheduled maintainence" has work lumped together without a clear description.
