When you say "root" do you mean the first root before a redirect, or after it?

|-Root
|---Folder A (where Joomla! was installed)
|---Folder B (where Joomla! now is installed)

I mean the folder where Joomla with JoomSEF is currently installed.

Understood.

In the following example, where would I manually place .htaccess 301 redirects for the old folder (A)? In the "Root" or "Folder A"? Does it matter, if so, describe. Thanks.

|-Root
|---Folder A (old site)
|---Folder B (Joomla! & JoomSEF installed here)

It shouldn't matter, but I think that better place is Folder A.

I'll ask the question another way: If you had a Joomla! install in subfolder "mydomain.com/joomla" and decided to move the install to the domain root "mydomain.com" could JoomSEF be used for .htaccess 301 redirects? If so, how?

In that case, if Joomla is running in root, there should be no problem using JoomSEF to edit the .htaccess file in the root directory.
If you want to create some 301 redirects manually, just follow JoomSEF's documentation in Edit .htaccess file section: www.artio.net/joomsef/documentation#htaccess
If you want to automatically redirect all URLs starting with /joomla/ to corresponding URLs without the /joomla/ part, you'll need to use the Advanced edit mode and create custom RewriteRules for that - this is out of scope of our free support, but we can configure it for you as a paid service.
