What documentation is currently accurate for this beyond the source
code? The only things I can quickly find are: "Design & Implementation
of FreeBSD 5.2" and "FreeBSD Architecture Handbook". The former is
getting quite old and I'm not sure how up-to-date the latter is kept.

Is the documentation at http://www.opensparc.net/opensparc-t1/index.html
and http://www.opensparc.net/opensparc-t2/index.html adequate for this
or is there additional information that is needed? Is there any tutorial
style documentation on the low-level T1/T2 details?

I've poked around the low-level details of FreeBSD/i386 and /Alpha in
the past, though I'm nothing like an expert at it. sun4v/sun4v is
only about twice the size of a 6th Edition kernel...

Is there a summary of the open issues somewhere? There are no sun4v
PRs open. http://wiki.freebsd.org/FreeBSD/sun4v effectively hasn't
been touched since November 2006 and suggests that the only critical
issue is lack of serial port support.
Please excuse any delays as the result of my ISP's inability to implement
an MTA that is either RFC2821-compliant or matches their claimed behaviour.
