The opening of that section (210.70) refers to one or more wall switch controlled lighting outlets. Please note that there is no limit on the number of lighting outlest, or the number of wall switches.
Likewise, in no place does the NEC define a switched receptacle as a "lighting outlet." The exception simply says that such a receptacle MAY be considered as a lighting outlet.
As for your second contention, a minor change in the 2008 language addresses this point. That is, IF you are counting that receptacle as one required by spacing, then you can switch only one half of that duplex receptacle. Otherwise, an additional receptacle would be needed.
