1) Grim Fandango is actually the only game fully supported as of today.
You can start and play Escape from Monkey Island and Myst 3, but expect bugs, glitches and even crashes.
I'm not sure about Riven, but I think that is still covered by the 2D part of scummvm, but not very complete either.
2)
https://buildbot.scummvm.org/builds.htmlYou can download daily builds from here.

But
...
The amigaos4 version is not tested by me and the last time I did download it, it was unusable due to a crash bug.
But you can, of course, test to your hearts content.
Edit:
3) I hope that the merge will bring more releases with the new additions (as long as I'm not running out of memory during compilation)
