In general yes. Most of cracks are done by changing the enter_game_name_here.exe, which is also changed in every patch. So if you patch, the game is no longer cracked and asks you for a CD or just won't run.
there are enough no-cd cracks out there,also you can crack it by yourself too.

Yes. The patch program wont see the game installed on your machine (since there is no trace of the game in your registry) and will refuse to install the patch.
depends on how the pirate version is distributed, but mostly wrong too, sadly enough.
