Wow...are you in for a surprise! By your description, this was BEFORE the renovations, which corrected all the problems outlined in your post. Please note: The A/C VENTS are completely adjustable. Merely "move" the exterior sections of vents horizontally, and the interior section of vents laterally. Very simple manipulations will easily direct the air flow just about anyway you prefer.
These rooms do have a sofa, but I am not sure if it is a sleeper. Alternatives would be day beds, which would be accommodated in this room type.
Gold SPG usually receives free upgrade to a "preferred view" (a balcony is an additional request). Club access was once a complimentary perk associated with Gold, but is now a standard amenity only offered free to Platinum SPG. Although I would still "ask" for the comp, as you never know unless you do.

In fact, it never hurts to ask for anything and everything you wish to have during your stay. Based upon availability, you just may receive your requests!
I'm currently Plat. SPG, and have been for eons. I LOVE the SPG program, and all the perks associated with this level of membership. Of course, above the standard expected, these vary depending on resort location. The Dolphin staff has consistently proved to be one of the BEST, with respect to guest satisfaction/requests.
Enjoy!!
