Yes you can, you import and add non-steam games to your Steam library. From within the library you can launch and run any games, although 'Steam achievements' will only be available for Steam enabled games.
Yes, some. Not all of them can be activated on Steam. See the related links for a list of the games that can be activated on Steam and for the instructions on how to activate a game on Steam.
You can't.
No, but there is a steam function to add non steam games on to your library.
You can buy a Mass Effect 2 Key for PC on Steam, Origin, or G2A.com.
Steam Games cannot be put on your laptop without a CD key. In order to play these games, you need to have the CD key available. This is because these games are still licensed.
It all depends on what games you like. I feel that steam is less intrusive and offers more choice than origin, but if their's a game on origin that you like, you have to buy from origin. It's as simple as that. Source: Di Vapor

Steam sends games electronically therefore you will need to download it. Most games come with the CD key embedded. The only game I have found to still need the CD key was ETQW (Enemy Territory: Quake Wars). But steam overlay gives the CD key to you when you open it and it asks for it. Hope this helps my steam account is Moo243 if anyone wants to add me.
Steam games store your product key on their game server, not your client software. As long as you legally purchased your game and created an account, you will just log in as usual. You do not need your product key again, even if you unistalled the game at some point.
This is possible, but only if the game already is available to buy from the Steam store. For example, if you have Half Life 1 from back when it was not on Steam, you can validate the CD key on Steam...and then play it without the disc through that. Games that Steam doesn't support however can not be translated over to Steam. Quite a few games are on Steam though, including EA recently adding a number of their games to it.
If the game is available On Steam (See links below) you can add the CD Key/serial number by selecting the Activate Product On Steam from the Steam Games menu. Otherwise you can try the Add Non-Steam game option which may or may not find the game in the Mac's drive.
Stargate Resistance is a Steam licensed product. If you did not purchase it with Steam you can download the 'Steam' program on their website http://store.steampowered.com/ After that you will be asked to create an account. Once you have completed these steps you will be able to register the games CD key with Steam.
