Ahh, now I understand. Does not matter.

iTunes and iPod don't care at all what transport underlies the TCP/IP  
network. Your 'network' in this instance is everything connected back  
to the Verizon router...your Airport devices are acting as wireless  
switches, not routers in this setup.

(Routers connect different networks, switches connect different parts  
of a single network.)

Your overall speed between any two nodes on the network will be  
limited by the slowest link, so the 802.11g will slow things down, but  
the 802.11n base station is connected to the network via 100 megabit  
ethernet..it will talk to your iPod at 802.11g speeds, but anything  
connected to it will talk to the internet at 802.11n speeds (actually  
whatever speed your internet is at, as even 802.11b networks can go  
faster than the average residential internet connection)

The only times that you'll slow down a wireless station is when the  
faster and slower device are connected to the same base station, here  
you're connecting on two different segments of your LAN, so it's ok.
