I did a search and couldn't find anything about this.

I noticed the names in the "fan club" credits on the EE for the Two Towers were different than Fellowship.

Is it too late to get my name on the ROTK EE DVD? How would I go about it?

The last time I heard, you had to be a Charter member of the official LOTR fanclub. You can get more info here.

You needed to buy a 3 year Charter membership for the LOTR Fan Club. That was a couple years ago. After the Charter period, you are SOL, sorry.

1 YR Membership = Name in FOTR
2 YR Membership = Name in FOTR + TT
3 YR Membership = Name in FOTR + TT + ROTK

flix1 is correct...you had to sign up as a charter member for three years (it was about $100) to get your name on all three EE. Look for me...I'm there!

I'm in there, but in the main credits...look under "Mr. McKellan's Fluffer"

I thought it was way cool to see Bill Amend, cartoonist from Fox Trot (who has tons of LOTR references in his strip), listed.

Any other famous names seen in there?

Several of the actors from the film are listed. Elijah Wood, Dominic Monaghan, Billy Boyd, and Ian McKellen. I'm not sure if any of the others are. I think Peter Jackson is also listed.

Suddenly the line "Would you let an old man carry his walking stick?" will forever have terrible implications for me.

Most people are unaware that Gandalf had a constant erection for the entire duration of the ring saga, but I'm glad they adapted that part of the book faithfully.
