Is that the final look of it or a different theme will be added? And instead of re-setting the password there, can we not just make a new(temp.) account to test it out?
The final theme will look similar. Some adjustments might be made.
You can create a separate account if you want.
err.... any way to get my password reset without an email?
No. You could create a separate account using a throwaway email service.
With the final version, there will be a way to move your account without having a valid email.
PMs?
I'm currently thinking that for security, PMs will not be automatically transferred over. Certainly, there will be a way to download your old PMs for at least a year after the transition, and maybe there will be a way to import these PMs into the new forum if you want. (I already have code written for exporting your PMs as an mbox file which you can import into eg. Thunderbird, though I haven't gotten around to creating all of the interface stuff for it yet.)
