So, I recently updated all the components in Eclispe (i.e. WST, JST, etc.) and now, I cannot open any JSPs. I can open classes or anything that's a .java file, but if I try to open a JSP, this is the error I get:

Error opening the editor.
No editor descriptor for id org.eclipse.jst.jsp.core.jspsource.source


Any ideas?

Updated how? An error message like this invariable points to a
broken installation or unsupported JRE.

I went to eclipse's downloads site (http://www.eclipse.org/downloads/) and downloaded the updated packages for the Eclipse Web Tools Platform Project, JDT and PDE as zips. I then unzipped them and copied the contents of the 'features' folder within the archive to the 'features' folder in Eclipse's install folder. I did likewise for the 'plugins' folders. When I read up on updating Eclipse, it said that was all you had to do to install new/updated packages. Is there any way i can check to see that I did that right?

That sort of installing-by-unzipping is a tough row to hoe. I suspect
you're missing pre-reqs such as emf and xsd models. Even then, just
getting features and plugins folders will be missing a LOT of the base
platform stuff, unless that's what you started with. Normally just a
plain unzip is sufficient.
But, your approach isn't really supported.

If you are just trying to edit JSPs to produce web apps, you'll make
life easier for yourself just getting the JEE IDE from
http://www.eclipse.org/downloads/

If you are trying to make some custom tool, then that's a whole other
question, but I'd recommend you'd start off with the Java EE IDE, then
you could diff the two installs to see what else you might be missing.
