How do I model a resistor array in SPICE?
Unless I musunderstood your question, you have the answers in the links you gave: simply make your resistors, each and everyone, with parameters enclosed in curly braces, {mc(1,0.1)}, bogus example. For temperature, simply add it after the value:

R1 pin1 pin2 {mc(1,0.1)} temp={mc(25,0.2)}

Don't forget that the temperature is not dynamic, it is not a function of time. So your array would look something like this:

R1 pin1 pin2 {mc(1,0.1)} temp={mc(25,0.1)}
R2 pin3 pin4 {mc(10k,0.001)} temp={mc(27,0.2)}
R3 pin5 pin6 {mc(2.7k,0.05)} temp={mc(-100,0.001)}
...


Or simply make the temperatures the same, {temp}, and add .param temp=mc(27,0.1), for example. That would make them all dependent on the same temperature.
