Does Retrospect/Retrospect Express compress this backup file-stream, so

Yes (but it can't reduce the size of a file that is already compressed,
like an mp3 or a jpeg).

And in case my drive crashes and I need to restore my backup, does my
hard-drive need a lot of additional space in order to place the backed
up data there? (sort of like a huge Zip file; you need free space for
the Zip file itself, and of course additional free space for the data
that comes out of the Zip file once decompressed).

I don't actually know. But you're right to assume that some scratch
space might be needed. If you really do have a crash and you need to
restore, though, it's going to help to have (you guessed it) an external
hard drive to start up from.

Finally, keeping in mind that Retrospect creates a single *stream* of
data, does that mean that in case you span it over several DVDs -if one
of the DVDs go bad, get damaged or whatever, I won't be able to salvage
any of the data on all the other DVDs either?

I don't think that would be the case, since there is a sort of "table of
contents" on your hard disk. However, I don't really know. m.
