Answer 1

It looks like your stuff is all in the wrong order. Some things:
If you don't have an L flag for a rewrite, the rules after will continue to process the rewritten request. So you want to use the L flag.
Rewrite conditions only apply to the immediately following rule, so you've got a condition that's just dangling somewhere and not being used.
The show_users.php rules will never work the way you've set things up, the regex pattern is the same, so no matter what, your requests will always go to show_staff.php.
Your rules aren't in the right order, two things need to happen if I'm guessing what you're trying to do. You need to match against a request with a php extension and externally redirect the browser, then you need to internally rewrite that request back to the URI with a php extension.
So something like:
RewriteEngine On
RewriteBase /
RewriteCond %{THE_REQUEST} \ /+([^/]+)\.php
RewriteRule ^ /%1 [L,R]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI}.php -f
ReweriteRule ^ %{REQUEST_URI}.php [L]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([a-zA-Z0-9-/]+)/?$ show_staff.php?url=$1 [L]

You can use this code in your DOCUMENT_ROOT/.htaccess file:
RewriteEngine On
RewriteBase /
## hide .php extension
RewriteCond %{THE_REQUEST} \s/+(.+?)\.php[\s?] [NC]
RewriteRule ^ /%1%2 [R=302,L,NE]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{DOCUMENT_ROOT}/$1\.php -f [NC]
RewriteRule ^(.+?)/?$ $1.php [L]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([a-zA-Z0-9/-]+)$ show_staff.php?url=$1 [L,QSA]
