Hi Alan,
I've gone from webhosting newbie to now running a
VPS Hosting and Semi-Dedicated from eUK. The one piece of advice I would offer you is to get cPanel and WHM (they come together). cPanel allows individual users to manage their entire account themselves through a GUI without you needing to interfere. The backend of that is WHM where you can do updates for things with a few clicks. You can do it all by SSH but I find it's a load easier to see everything is update through a few screens in WHM.
