Heyyo,
Ok, first off yes you do have to install steam, to make it easier and faster just download steam with CS1.6 cached:

Then let it update.. could take a few hrs or more knowing steam (yes, many of us are also frustrated with it..)....
After that? just install Joebot. Now, I'm sure aspirin already updated his Joebot to work with the latest CS1.6 steam update that screws up pretty much all bots, if not you can nag him ti'll he does.
