To upload and install plugings, download the plugin you want, unzip it, if it simply a singl .xml file all you need to do is unzip it to your desktop, then go to your vbulletin admincp>plugins and products>product manager>click add product at the bottom, them you will see import product, click that and choose your plugins .xml. and upload.

If it is more complicated plugin you may have to install things to your root, if you are only running vbulletin cms on your site, then your root is probably 'public_html' uploading it there should work. Some plugins may come with multiple folders you need to upload like 'images' 'includes' when you see this simply upload the entire folder into the according folder of your vbulletin..

There should be more easy tutorials on such things but around here, everyone is presumed to be a vbulletin pro so getting easy answers to the simpler things like this often go overlooked..
