Best practice 301'ing latin domain to internationalised domain

[Asia_Expat]

One of my sites is in English and Thai. The Thai pages are in subdirectories of the main .com...
However, I've decided to invest in the .th ccTLD for the Thai pages. In March, I'll be able to start using the internationalised version of the .th... so I'm wondering what are the potential technical issues of 301'ing the Thai pages to the new internationalised ccTLD?

I mean, should I just redirect to the punycode, or to the Thai script. Seriously, I really don't know...
And what about the www... Could/should I drop it altogether?

OK well the Thai script ccTLD is currently in sunrise and I'll have the Thai version of my domain up and running in March (thnic have already confirmed it's mine) I'll do some experimenting and try and remember to update this thread.
