Con Packing List?

Okay, the annual Anime Con in Denver, CO is coming up next weekend!  Last year, the 2009 edition was my first ever Con!  This year, I'm more prepared (or am I?)

Live in the area?  COME ON FOR GOSH SAKES: ndkdenver.org/

So I'm making my packing list for the weekend (I live in town, so I can take different things every day)... what should I make sure I bring?  Here's what's on my list so far:

DVD to be Autographed (Voice of Ranma will be there <3) - may or may not want to wait in line for this, but just in case!
Clipboard and paper, pencils, pens - for Devmeet (!!!!!) I've never done one before, and hopefully I can make it and do some im-promptu art trades??  Anyone else coming, check it out: nan-desu-kan.deviantart.com/bl…
Backpack with Snacks
Hats to Sell??? (thinking about taking my extra "testing" fleece animal-ear hats from the past year to sell for like $5 each... not sure if that's illegal or what, but worth a shot??)
Highlighter to map out my schedule of events
Camera!!!  + extra batteries!!!  + video camera too?  Possibly?
Lots of money!!!
ID so I can get my drink on at the bar!! (Imma need it.  Last year I remember being surrounded by teenagers and thinking "MUST. HAVE. LIQUOR.")
Rocket Costume and accessories!! (belt, hat, whip (for Rocket Grunt v.1), Pokeballs, Pokemon, Pokewalker, DS)  Should I take a big Pokemon too?  I have a big, life-size stuffed Turtwig - should I bring him along?
Extra pair of shoes in case/when my boots get too uncomfortable
Change of clothes to a normal person - for when I have to leave (Grandma's b-day lunch on Saturday, picnic with neighbors on Sunday)
Cell phone - with numbers for my friends attending! (yay, this year I'm not going alone! xD)

I'm also thinking about reviving my costume from last year for the last day, simply because I don't know if I want to wear the same outfit three days in a row AND because my Team Rocket partner won't be there on Sunday.  This is what I was last year: img.youtube.com/vi/9FlSGTV6was… - her, with that diary, in her work uniform

For the record, no one knew who I was last year xD  But I put a decent amount of effort into that costume, dammit!

Also... any suggestions on how to do my hair for the Rocket costume?  I was thinking about using the gel/waxy stuff I have to spike the ends to make it look more Anime.  Should I wear it down and spiked... or in pigtails and spiked...?

Anyways, I'm bummed that I have to skip out for some things, but I'm going to make the most of what I can.  (and I'm going to cry if I miss the Avatar, Ouran, or Pokemon photoshoot!!  ;__; )
