At first, if you want to be good skilled player you MUST have your own config.cfg. I personally don't use any other scripts (accept buy script), only my config in combination with my Logitech G15 keyboard.

- config.cfg you will find in your counter-strike source folder, something like this:

D:\Installed Games\STEAM\SteamApps\account_name\counter-strike source\cstrike\cfg\

...and you can edit it with Notepad or Wordpad.

G o o g l e it...

I will not write down every detail, because in one way I want that You by yourself figure it out what can you do with config.cfg

-Here you can see my config, maybe it will help you to configure your Own config.cfg
