After Effects Advice

I have an introduction to a fashion show to complete for friday. Its going to be really tough but i was wondering if anyone was good with after effects and would be available to give me any advice or small bits of tidbits if i get stuck somewhere.

I do have an immediate question tho. What resoultion should i be working in. Ive done some small stuff in after effect for flash but nothing that was going to go straight to a projector(like this is). Should i do it at 1024X576? or something else

thanks for your help
