Ideas For A Party

I am 13, turning 14 on May 26th. I have never had a party before and could really use some tips. I am practically planning this party by myself.
Heres what I had in mind for the party:
Music (of course)
Pool
Some games (e.x - twister, volleyball, soccer)
Some small activities (e.x - "worm in a pie" and "dougnut in a tree" [ they`re games I found on the internet])
BarBQ
And hopefully... Dancing.
I want a wild party that wont go too far. Do you think I need anything else? Please help.
