Feed of WordPress on Main page

Hey all,

My WordPress is hosted on http://seventh-element.com/blogs, yet I would like to have it so I can have a feed of my recent posts on my main page, index.html.

Is there a code that I could use to do that? And if so, can I have it so I can have feeds of say, a certain category in one place on the page, and another category on another?

Get back to me, please =)
Ben
