I want to teach myself kickboxing...?

I recently decided I wanted to take up kickboxing and figured I could teach myself. It was when I was searching for a punching bag and other things when I realized I have no idea what to get. How do I know what weight of bag or what kind of gloves or hand wraps (if I need any) to get? And any recommendations on training DVDs and trusted brands of equipment? Thanks in advance!! :)
