from the case you have gotten if you purchased it from steam you dont need it it will install just fine if you have illigaly downloaded the copy you will have to search for it on the web which is super hard to find it violates the copy rights.
To plant a bomb in Counter Strike 1.6, find a bomb site, select the C-4 bomb in the weapons slot (default is 5), crouch, and press and hold the primary attack key until the bomb is planted. While the bomb is being planted, a progress bar should appear in the middle of the screen. Just be warned that there may be enemy Counter-Terrorists who are patrolling or hiding in the bomb sites so make sure you flush them out of hiding and eliminate them.
It's like asking "hey guys, what do I type in at the 'password' field?" With XP, there should be a CD in your documentation packet. On it is a 16 digit alpha-numeric code and this is your Product Key. If it only has 12, then try that.
You need to convert the picture to a .wad file and name it tempdecal.wad. It must be a size divisble by 16. (ex: 16x16, 96x96, etc) Put the file into C:\Program Files\Valve\Steam\SteamApps\<username>\Counter-Strike\cstrike\ Then right click it, enter properties, and make it "read only". Now you can spray the picture inside the game.
