EP Installation Order - Does It Matter? [SOLVED]

Hello, all. I read the "How to Install The Sims 3 Correctly" thread very carefully and performed a search but my specific question was not answered.

Let's say I have already got the base game and all the EPs/SPs I want. The "How to" thread says to then install the base game, then the EPs/SPs all at once, then run the latest manual patch, then use the Ultimate fix. Now, I don't really care for the Supernatual EP so I didn't get it. But what happens if later, I decide I want it after all? How do I install it? Is it as simple as just installing it like I would the other EPs, then re-applying the manual patch and Ultimate fix? The thread I found said it's better to install all EPs and SPs at the beginning, so would I have to uninstall EVERYTHING and start over, but this time installing Supernatural along with the others, before applying the manual patch and Ultimate fix?

Great, thanks for clearing that up! Bandwidth caps are the bane of my existence when I'm eager to start playing. So now I can start with the base game and get the EPs at my leisure, installing them as they arrive.
