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.
Sagging porch lines are common on older homes. This is typically a result of poor foundation work or no foundation at all. Over time, old-school wooden pier-style supports rot out or sink, giving the porch a sag in the middle. There are specific products used to replace rotten or failing porch supports.
