Integrating Wordpress Into Site-Only front page!!!

I am in need of a simple wordpress integration. I can't seem to get this figured out but I do need it done TODAY (within 1 day please!) Timely bidders only! All I am in need of is for my index page to load my wordpress entries (wordpress is located in a sub folder) (say 3 entries and then they archive)- I want all of my other pages to stay the same and simple be part of my normal site. I want to be able to update my blog and it post to the index page. (and also be able to comment on them within the site) Thanks!
