As far as length.. I think that should include the trailer tongue? As I understand it for our wheelbase length, the rule of thumb max trailer length is 28' (20' + 1' of trailer for every 4" of truck wheel base over 120").
Unfortunately, I haven't shopped trailers in the 8 years since we bought our current rig. That said...
I would suggest that you worry much more about weight than length. The wheelbase rule of thumb has been kicked around for years and seems, at least from what I've seen, to have roots in an old towing article with little scientific basis. Ford doesn't issue such ratios, and someone can correct me if I'm wrong, but I don't believe the other major truck carriers do either. Your calculations above have you on the right track.
FWIW - I tow a 35' trailer with the same set-up as you with the exception that we intentionally skimped on options so that we would have more payload to work with. The length doesn't bother me at all. With the trailer loaded at 8k pounds, I make sure the tongue is between 1,000 and 1,100 pounds. With almost 1,900 pounds of payload available on the truck, that load keeps us just below our GVWR.
