But, it says it's a 32bit CPU... So does that mean, the NetDuino, can read in Full 16bit or even 32bit data digital streams from ADC to DAC ?
No. "32bit CPU", in the vast majority of cases, refers to the size of the internal data bus. In other words, the CPU can process 32 bits of data in a single instruction. But everything else (like an ADC) can be any size.
The AVR / Arduino processors are 8 bit CPUs. This means that the internal data bus is 8 bits wide; that the CPU can process 8 bits of data in a single instruction.
