Removing various apps / progs

I installed Mira an app that you can use with the remote, however it has installed itself in the pref. panel how do i remove it.

Also I added a few automater tasks so when i right click then automater they are in there how do i remve these?

You should find Mira either here:

Macintosh HD ---> Library ---> PreferencePanes

or:

Macintosh HD ---> Users ---> Your User Account ---> Library ---> PreferencePanes

The Automator scripts would be here:

Macintosh HD ---> Library ---> Application Support ---> Apple ---> Automator

And then poke around in there. Since I didn't install any other scripts I only have a Workflow folder with stuff related to iPhoto in it. And you could always follow the same path in your user account, there might be some Automator stuff installed there (Application Support ---> Apple).
