First time halloween party, help?!?!

hey I am planning on hosting a little halloween party at my house and I'm going to decorate my shed up for it and was wondering if any one had any ideas at all, including:
Food
Music
Games
Decorations
or any other tips and ideas to throw a fun...

teenage party! I'ts my first time, hoping it will go well but the people I plan on inviting are old classmates and friends that I havn't seen in quite a while so this is hard lol. please help me out?!?!? your friend, trish

Decorations: Neat idea I saw - create tombstones of those invitied and make a graveyard out of your backyard - buy styrofoam curved like a headstone - spray paint gray - carve out their names and a saying underneath - spotlight shining towards the gravestones...Have fun !!

have rap music, junk food, bord games, and any kinda scary decorations you can find! when is haloween? you have like a month I think...

well it all depends on the age of the kids.
id say lighting is especially key..assuming your going to have the party at night... get strobe lights..black lights...glow sticks...
make sure theres some chairs but not enough for everyone...forcing some guests to walk around and mingle...
food isnt hard...just soda...umm energy drink would be good but that can get expensive..mountaindew is always good... candy..some chips...pizza, burgers, or hot-dogs are fine..
but as far as entertainment goes I'd say go for rock music as opposed to any slow, rb pop or rap songs.. try to mix in some heavier stuff like Korn, disturbed and slipknot.. along with 3 days grace... my chemical romance..stuff like that and playing man-hunt with teams is always cool in the dark especially if everyone has a glowstick necklace[like a glowstick with ribbon or something] and you get 2 colors[for the two teams] and a well planned prank is always good to get your parents in on... something to come scare all of your friends...
have your parents come out in all black costume while you guys are playing man hunt and sneak up on you guys purposely fall behind and have one of your parentsmasked person drag you off then go back to the shed and reveal you little secret...

or having your parents or a few guests create odd noises from outside the shed could even get some of your guests a little hyped up

and as logn as none of your guests are really religious I suggest a quigi board or having a saonce

good luck
