What cables do I need for a nikon d3100?

Well I'm about to buy that camera but what kind of cables do I need to see videos and pictures on my Mac. I really wan to see videos on my hdtv so what cable do i need? A hdmi? Next how can I put photos on my flash drive? Does it read it or it doesn't? Also my most important question (I repeated it) how can I see photos on my computer. I'm not buying a kit. Just the regular camera and that is it.

The camera comes with USB (to computer, the computer sees it as an extra hard drive) and maybe HDMI cables - along with battery, mains lead, charger and software.

If you have to buy the HDMI cable separately, your dealer can help.
