You need to download Gmod 9.0.4c when you start there will be 3 choose unmark the Gmod 9.0.4b and your set to go and play gmod 9 online.
NO
you can use gmod in any way you like its pretty much a free roam game where you can spawn things and download addons the gmod website its an awsome game hope you enjoy! p.s. if you dont have a steam account you cant play gmod and you also need a game source by lolkid007
No you can not
gmod 9, yes gmod 10-no
No, you do not need to be on the game you bought with Gmod to play it although you do need to have the game installed to run gmod and i also recommend having the game Half-Life 2 installed to get most of the textures and weapons and npcs and props that go along with it.

Get a new PC.
You can, click on the multyplayer button and click on the server you want to play in. It takes time to load
yes but it is illegal and you can't download addons steam can also trace you if you play gmod without steam for prolonged periods of time so I recommend not using a pirated copy of gmod. it is also likely that you can't play online based on other reports of pirated copies and besides nobody likes a pirater
