From the link you posted it says to drag and drop the folder to places, as in your pic, but above you say not to do that. I'm confused- and afraid I'll REALLY mess things up!
Sorry for the confusion.
You should not move (via drag and drop) the applications folder to another location, like
Macintosh HD / Users / YourUserName / for example.
The Sidebar (Device, Places and Search) are not actual locations like in the sense, that they (files and folders) reside there, it is a place to hold aliases of actual files and folders.
When you drag a file or folder (like the original and standard Applications folder for instance) to the Sidebar under Places, the folder or file will not be moved to a different location, it will stay where it is. The Sidebar is just a place to hold aliases.
I think this answers my question, but shouldn't I be able to get to the link by putting the folder there with the wordpress folder inside? Maybe a broken link is not the problem? Maybe I did something else to cause the problem.
Does that mean, you can use the actual Wordpress application, but the document you worked on, is gone?
So is it ok to drag and drop the application folder to the "places"?
Yes.
Is this something you need to install? I'm assuming it's not something I can use after the fact, but I would help in the future if I have this problem again?
No, Time Machine comes with Mac OS X 10.5 Leopard and 10.6 Snow Leopard. You just need an external HDD and go to System Preferences > Time Machine and select that external HDD to be used as backup.

Thanks again for your help.
No problem.
OH, I just remembered something! When I saw that the application folder was empty, I noticed I had an application folder in my dock. I draged it to the where I thought it should be, under my user name, but it dinged and disappeared. Can I drag and drop it back there? Since I had the problem loging in before I noticed this, it probably won't work, but it's worth a try!
You dragged another alias of the Applications folder from the Dock this time. To get it back, use the same method as with the Sidebar, but drag the folder to the right side of the Dock separator.
