Not necessarily. If you own absolutely no Source games at all, then you can buy it, and you can then run Garry's Mod. A lot of Garry's Mod addons require Counter-Strike Source though, so it's recommended, not required.

Plenty of people play Counter Strike. After all, its a great and entertaining classic.
to play counter strike of course
After you downloaded Counter Strike, you double click on the shortcut of the game (normally located at the desktop) and you should be able to play... If you meant "How to play and be a pro and Counter-Strike" , then I strongly suggest you follow veteran players' advice, practice, and look up at the Counter Strike Wiki.
Download steam from steampowered.com and search for counter-strike source
A large number of people around the world play Counter-Strike or a form of the game.
No, Counter-Strike: Source is a one-time fee.
