Hi Lawrence, thanks for the advice. 

We have been planning on wet cellulose but we're having trouble finding 
a contractor.  We do plan to wrap with Tyvek immediately after 
sheathing, as we are quite worried about the rain.  Once it starts on 
the northern California coast it doesn't really stop until April, 
although February was dry this past year. 

We want the winter to work on the interior.  I like the idea of doing 
this from the outside, but as it will probably be raining, the inside is 
more likely.  :)  We will be pouring the perimeter early next week, to 
give you an idea of where we are right now.

We are also debating when to put it in.  I would like to sheathe the 
outside and wrap, and then let the inside just breathe for a while, as 
we are using a lot of lumber that we milled onsite and it is very green 
and wet.  It's one thing to have "breatheable" walls, but another to 
actually seal up the wall before the moisture level is down as far as it 
can go.

What do you think of the idea of running all wires in conduit, as some 
folks do with cellulose?  We won't have any plumbing in outside walls, 
but if so I would probably sleeve it to make it easier (possible) to fix 
later on.  I imagine pulling a cellulose wall apart is a bit messier 
than one stuffed with batts.  I'll definitely run communications wires 
in conduit, but haven't decided about romex yet.

thanks again
