I just gave this a shot using only the TcpAckFrequency and it seems to have taken my ping from in the 250s to in the 190s for a single instance of WoW (Charter cable is terrible btw). I couldn't find the folder for TCPNoDelay so I didn't bother with it.
It's the same registry key (folder). You have to create a DWORD value if it's not already present.
