I've got one question: how do I make areas names in CS:S??? Official
maps have names as "dobledoors", "bombside 'A'" and others... It shows
on green color when we are sending messages in "teamsay".

It's done with the navigation mesh. Here's a link to it in the Valve developer wiki:

http://developer.valvesoftware.com/wiki/Bot_Navigation_for_Counter-Strike:Source#Adding_Place_Names

Summary:

You'll need to enable sv_cheats, then nav_edit 1<span style="font-family: monospace;">. </span>nav_place_names
will give you a list of the names used by the bot chatter system. Once
you've got the place name you want type nav_use_place <name>,
point at an area you want to label and type nav_toggle_place_painting.
This will 'paint' the name to any areas you point at with your
crosshair. When you're done with one name type
nav_toggle_place_painting again to turn it off, then repeat the process
for other areas.
