I hope I will be there too, I am geared up now. (Except for arrows, I don't have that many but I will check the shops and buy some before the battle)
There should be some but you will have to pay outrageous prices (like 20-40 cents each) I think the fight has run the market dry.
Made full diamond armor prot 3 minimum inventory full of potions power 3 bow sharpness 4 diamond sword bring it on dragon. (plus more gear)
Have fun at the fight today everyone and good luck. I will unfortunately not be able to attend today. Once you have the dragon slayed, keep back from the dragon egg so @JackenKracken can get it. We will be placing it at the Atlantis spawn for all to see. Make sure to bring your glass bottles to pick up some dragons breath. I'd suggest not to kill the dragon too soon so that you can harvest some dragons breath. Have fun exploring the End and hope you can find some nice End City's. I believe @c0wg0d will also be opening the resource world End, so you can have another dragon fight there too.
