Blog article on front page

Permalink
On my website:http://www.anakwaana.com/akatest... I have three columns on the bottom of the front page. Here I want to have three blog posts (just showing the first 4 lines and with a "read more" link). I am using Simple Blog.

How do I do this? Also, in the sidebar, I want a link to the two last blog articles (that updates when a new article has been posted). How do I do this?
