in what way?

Yes, garry's mod will work with portal and you will have all the HL2 stuff.
No
No, The Orange Box does not include Garry's Mod (instead it has HL2, HL2 EP 1 and 2, Portal and TF2). I wish it did have Garry's Mod.
If you are running on Windows Vista or higher, please run the program as an administrator. Also, make sure you are launching the game through Steam, nothing else will work! If none of these work, I highly recommend you uninstall, redownload, and reinstall the program through Steam instead of fiddling around with the settings and messing up your whole Steam Engine.
In general you only get props in Garry's Mod if they exist on your system, or in other words if you have that particular Source game installed. Whilst Portal might contain some generic Source props (and Garry's Mod may supply some itself) it's entirely likely that some (if not most) of the HL2 props will be missing if you don't have HL2
As long as you have ANY source game excluding deathmatch, you can play. But please note that you will usually need a lot of source games to see other people's props that come from other source games.
chances are your firewall is blocking communication of the HL2.exe, either create an exception for hl2.exe or temporarily turn off your firewall.
10.00 dollars and it needs a source to play from so i would recomend hl2
You can't use any firearm as a melee weapon in Half life 2.
They don't really have a name. They just call themselves rebels. Their logo appears to be the lambda.
