YEP! They sure do. I don't remeber about the noise makers, but we still have our hats from when we went 5 years ago. I have been to WDW 8 times, planning my 9th & 10th trips now, but NYE at EPCOT was one of the MOST memorable nights, and absolutely the best NYE I've ever had. WOW, WHAT A PARTY!!! Even though the crowds were absolutely horrendous, I wouldn't hesistate to go again. There was so much entertainment. It was great. I hope you aren't driving your own vehicle there to the park though, it took us 2 hrs+ to get out of the parking lot, and I'm not joking or exaggerating.
The hats were like top hats, all different colors were available.
I know you will, but have a great time!
