Re: gas pipe through heat duct
Using 2009 unmmended IRC, Chapter 24 Fuel Gas, because I'm being quick and not taking the time to check your specific locale, which I suspect uses RCNYS and I forget what parts of which standard fuel gas code it ammends (NFPA 54 or IFGC) and not taking the time to check the Uniform codes.
quick first, easiest prohibition:
Chapter 24 - Fuel Gas
SECTION G2415 (404) PIPING SYSTEM INSTALLATION
G2415 (404.1) Prohibited locations. Piping shall not be installed in or through a ducted supply, return or exhaust, or a clothes chute, chimney or gas vent, dumbwaiter or elevator shaft. Piping installed downstream of the point of delivery shall not extend through any townhouse unit other than the unit served by such piping.

technically, I believe you have pictured a return air plenum receiving return air from floor(s) above and recieving air from more than one opening/duct.
