Any GBA regulars builders in SoCal?

Can't remember who (if anyone) here builds in LA. If anyone here does and wants to give me contact info for outside the forum, that'd be great. I have a few questions, and details for that area are a lot less familiar to me than here (Minnesota). Thanks.

Double-stud wall insulation methods

We are building a new house in Wisconsin, zone 6, and are planning on using double wall construction, originally with dense-pack cellulose. None of the local insulators that we have talked to will install the cellulose.

I am still searching for another insulator, but in the meanwhile I have been considering a flash and batt method with 3 to 4 inches of spray polyurethane closed cell foam on the exterior side of the wall and either batt insulation or blown-in fiberglass making up the remaining cavity.

Should we insulate the attic floor or roof where attic contains AC system only?

We have an uninhabited attic space (roof slope too low) that has a high velocity AC system air handler and distribution in attic space with blown in insulation between attic floor joists. Heating is a conventional hot water system with boiler in the basement. The attic is vented with both soffit and ridge vents; attic temperatures currently max out around 125 degrees where we live in southeast Michigan.

How do I rough-in a ceiling service cavity before inspection and insulation?

My addition that I am building has 9 foot ceilings, but I want 8 foot ceilings in the bathroom and I want to keep the two bath ventilation fans and the can lights inside the building envelope. So, I decided to create a soffit that essentially covers the entire ceiling (or a service cavity, I'm not sure what it would be called). The OSB attached to the bottom of the ceiling joists and around the top of the walls will be caulked and taped to create an air tight seal.

WOOD STOVE INSTALL AND EXTERIOR FOAM BOARD INSULATION

If I want to install a wood stove through the wall or the roof and both have 6" of foam board on the exterior, are there additional precautions to prevent exhaust heat duct from melting or causing a fire around the insulation? For example, install one or more layers of cement board over the 6" of foam. Then install through the wall or roof duct work.
