File permissions

When using the file manager I'm sometimes perplexed by what Revo Manager will let me do and what it won't let me do. Can I assume that if I create an admistrative user in Manager with the same user name and password as my FTP server that I'll be able to do everything in Revo File Manager that I can do from my FTP client?

That depends on your site server configuration. It would only be coincidental if it does; MODx users have nothing at all to do with your FTP user.

If your site server is configured to use some kind of suPHP or suexec, when the web server requests a .php script it will "switch user" to the owner of the .php file, which is your FTP user. Then you can write and delete files and upload to the directories.

If your site doesn't use suPHP or suexec, then when the web server runs a .php file it will be run as the web server user (nobody, www, apache - whatever the server is configured to use as the web server's user). Then it all depends on the permissions on the files and folders. If they can be written by other users beside their owner (your FTP user) then another user like the Apache user can modify them. If the permissions are such that only the owner can write to them, then the Apache user can't modify them, nor can it upload files to the directories.

Again, MODx users are only used by MODx; they have nothing at all to do with your FTP user, nor does your FTP user have anything to do with MODx.
