Reply to First set here I go. 6 hours long... need some wise advice.

Ok DJTTers,

I've created this thread to seek some advice for such a long set from 7pm till 1am this coming Friday 21th, my first time ever DJing out at a house party to celebrate the end Year 12 for my school year.
I'm downloading tracks like there's no tomorrow, simply because I don't have enough music!
I dunno if I wanna use Traktor or not with my Pioneer 400s setup. I don't know how to use it well enough. Should I?

Here's my plan.

Warm up: 1.5hrs with Deep house.
Then play Electro house/House for 1.5~2hrs.
Bangers/hits for ~2hrs
Then progressive house to finish off.

Obviously Im a noob, so I need to plan out my first set. How does it sound? Any tips to improve, especially for such a long set would be appreciated! One of my mates going to da party is a bedroom DJ as well, so that's my chance to have a short break, socialise with friends, then back to work.
I will not drink, cos I do not drink alcohol!
I volunteered to do this, Im feeling the pressure already.

I'll post up a few pics from the party and tell you guys and gurls how it went.

Cheers everyone.
