any way to disable metas on single posts?

You’d have to do it like this:

.postid-x .class {
   display: none;
}

Where x is the post id.

You need to find the id (in the html) for that post in the home page (using something like firebug), and then change it like so:

#myid .class {
display: none;
}

Here’s a link to a screencast on how to use Firebug: http://css-tricks.com/video-screencasts/15-introduction-to-firebug/
