WordPress Posts into Otherwise Independent Site

I’ll try to make this post as quick and clear as possible:

I am using WordPress for a blog-site and love it.

I would like to integrate a single-category of WordPress posts from this blog to another site–on the same server and sharing the same database–WITHOUT bringing over things like the header, sidebars, etc. Essentially, I just want the content “meat” of the blog (and to retain the ability for comments/etc).

I’ve been trying to just pull the contents of the page.php into a column on my alternate site…but continually run into ‘undefined function’ problems. I’ve been searching through and adding ‘include’ commands where and when I can find the functions that are missing…but I’m hoping there is some sort of general definition and include file for WordPress? (If there is, I can’t find it).

Anyway…help me out…essentially I have my own page…and want to fit WordPress posts into:

(my own headers, menus, style, etc)
<div col2=”mywordpress”>
//whatever is necessary here
</div>
(my own footer)

I do not want to use an iframe to include an entire blog-site…I would then end up with the sidebars and title that I don’t want.

Yes, I could use some basic WYSIWYG and have a much easier integration…but since I already use WordPress for a full blog, I’d like to just admin everything from one spot…
