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.
Metal will cost you WAY more than wood. Your cost will depend a lot on whether you are tied down to fixed spacing (leaving current posts, like porch roof support posts railings will have to fit between with uneven spacings), or if all posts are going away so you can use standard ized length pre-manufactured sections.
