I don't know if anyone's documented this yet, so here's the steps:

You close a blog by editing it and unchecking the "Commenting" option. In order for this edit to show up in the Recent Changes list, you have to also change at least one character in the blog, so I typically add a space somewhere. If you don't do that, disabling commenting still occurs, but it's kind of invisible. Even putting something in the Edit Summary doesn't make it show up in that list unless you also do that change at least one character step.

I go a step further and change the category so that if people are skimming the Blog posts category, these old ones are not listed and they can participate in the ones that are still active.

The person that created the blog can still edit it and could re-open the blog for commenting. If you want to prevent that, you do have to protect the blog with the admin-only protection level.

It doesn't look like you can rename a thread. About the closest you could come to that would be to create the blog under your own account, and then you can rename it to be under their account. The history will show it was made by you, but otherwise it will appear to have been created by them.

Then, to delete the thread, so this:
 * 1) Hover the mouse over the lower-right corner to make the More button appear, then click on the triangle and then "Remove".
 * 2) Type in the reason you're removing it, such as "moving content to a blog", then click the Remove button.
 * 3) Refresh the page to bring back the message, which will now have the notice at the top saying it was removed.
 * 4) Move the mouse to the lower-right corner again. The More button will now have a Delete option.
 * 5) Fill in the same reason and click Delete.
