Replying to Camera Advice

Whats up guys. I am looking to purchase a dslr camera.

I mainly want to shoot skiing (film and photos) and cars with an HD camera. My budget is around 500$ for a total package including lens, body, memory, batteries. Was also looking to drop some money on A stabilizer and maybe a mic.

I want to keep it relatively simple as I can use a camera somewhat well but most of my friends can't.

What would you recommend for a camera and lens?
Where should I look for the best deals?
Any good sites to learn about shooting?

Thanks guys!
