Twisted is only needed in dom0 -- you can't use NetBSD in dom0.

These should all work, alternatively you could use an install kernel
which includes a ramdisk with sysinst.  I have built such a kernel,
you can grab it from:
Sysinst in this image is tweaked to give saner choices for installing
a Xen unprivileged domain.

No, the NetBSD tree includes support for Xen 1.2, I'm reluctant to checkin
support for Xen 2.0 since there's no support for running NetBSD as dom0.

> What is the suggested NetBSD userland  (NetBSD 2.0 RC4)?

Any userland from the 2.0 branch should be fine.  I'll probably update
the NetBSD sparse tree to a new snapshot soon since NetBSD 2.0 has been
tagged now.
