Reply to Gig music advice! Please help!

I have a gig for about 50-75 13-year-olds.I have been getting music from the top 40's but not sure how to mix that stuff (well). Does anyone know of any good youtube tutorials for this? I mainly mix house/electro... are there techniques similar to mixing electro and house that I can use in music for this gig? ALso where can I find some more stuff that 13-year-olds will like (while keeping the parents happy *no dubstep or at least no heavy dubstep*) Also what about mashups and I need to keep the music clean, no explicits.

Here are some samples of my mixing.
