I’m going to come across a bit cold hearted here and say ‘Google Is Your Friend’. You will need to research these aspects to get familiar with what you need to do, this forum is for BP support and guiding on how to install a site to a server is a little outside of it’s remit (WP codex may have some guides?)

Essentially your hosts are only saying what they all will, when you set up a shared hosting account you are provided with a control panel along with url and login plus ftp access to your web directory.

CPanel is designed to be used by non technical users, it is a point and click interface to server management and pretty easy to use, you just need to spend a little time familiarizing yourself with it. For ftp you will need a client e.g filezilla to use to upload your site files (or you can use the cPanel filemanager upload capabilities, either way it’s not hugely difficult. Your database will also be set up via cPanel, then it’s simply a case of running the WP installer when the site files are in place and you have pointed a domain name to your provided IP.
