It depends on the quality of the sound card, just as much as on the
quality of the amplifier, speakers or any other component you use for
your music playback.

Yes. You might get better sound quality with a better sound card and/or
better cables, though. The cable, however, is a cheap solution (compared
to buying better equipment), though you might just give it a try and
find out whether it suits your needs.

Certainly not. At best it is equally bad. (On the other hand, apparently
most people don't mind listening to music at low sound quality).
I use *professional* grade sound cards, because I like good sound quality.

Buy a high quality sound card. Since I mostly use laptops for this, I
prefer external usb sound cards. Nowadays some have DA-converters
matching those of the best high end CD players at a fraction of the price.

It depends how you rip them (what format). mp3 has some qualtiy loss,
but at the higher quality settings this won't matter on most hifi
equipment. There's the option to rip it lossless as well, ie. with
exactly the same digital quality as on CD.

Purely digital at constant timing.
