No. Left 4 Dead Xbox Live Players can only play with other Xbox players. The same goes for PC.

You can no longer play original Xbox games on Xbox Live.
Xbox live co-op means that you can play a story or other missions other Xbox live with friends or random people.
They are the same but on Xbox Live games, you can go on Xbox Live (online) and play against other people from around the world. Xbox Games that do not have Live you cannot. But it is no big worry =]
Depends on what your wanting to do. Xbox live will allow you to search and play matches with people around the globe. Without xbox live you can still do split screen or lan matches. lan/system link
