Re: tying the porch roof into the main house... I'll add I'd also go with 5/8 CDX ply for the roof sheathing. That added 1/8 goes a long way to resist uplift , and as you know wind in your area is a BIG issue.
The portion of the rafter that overhangs the edge of the porch is called the rafter tail, and in order to keep water from running off the roof and falling directly onto the porch and its foundation, the rafter tails should extend at least a foot past the porch wall.
