No, not yet. They have to jailbreak 1.1.3 to find the new apps. But it will probably be the first thing to be downloadable on the 1.1.1 and 1.1.2
The answer is quite likely to be yes. But it's a bit of a moot point, as if you can copy the 5 apps then you can jailbreak the 1.1.3 firmware anyway.
Basicaly, you don't need to jailbreak the iPod, to get the iPhone apps, you can extract it from the firmware, open it and decrypt some files with vfdecrypt... like the 1.1.2 firmware, but, the vfdecrypt isn't support 1.1.3 yet...
