What I'm trying to do is display a single post in a template that I will use for the home page. I am hoping to do this by flagging it in a category "sticky".

Caveats
1. I am not looking for a simple loop that displays just one of the posts (or am I?).
2. The post will have the standard comments below it to enter new comments.

I guess what I'm looking for is something similar to the "single.php" template, however, grabbing the post with a category, not id....
