Since you asked for a tutorial to help you become a pro, I seriously recommend you try an easy to use and well documented distro which has an easy upgrade path to a more advanced cousin which is professionally used.
An example is Fedora. It has step-by-step tutorials for EVERYTHING, and at the same time its stable brother is Red Hat Enterprise Linux, the distro you will be most probably using if you use linux in official environments (All webhosts with cPanel usually use RHEL or CentOS (a RHEL clone)).
OR, install ubuntu. Its simple enough to NOT want much linux knowledge and learning it will help you graduate to Debian GNU/Linux, the other server-grade linux distro commonly used in professional environments (for eg, IISc (Indian Institute of Science) has all its computers running Debian Stable).
But I don't recommend some other easy to use distros like SuSE, which tries too hard to hide the internals, or MEPIS or DreamLinux, which is not sufficiently documented or has a large enough user base to help you instantly with all your problems.
Nor do I recommend you start with distros like Slackware, ArchLinux, Linux From Scratch, CRUX or Gentoo which need you to work very hard from a newbie state to even begin using them.
