You will definitely need to install a tranny cooler. I have a supercharger in my Runner and am pleased with the performance gains.
Here's what I needed to do and what I plan to do:
Installation of the S/C will most likely cause preignition or pinging. You will need to run at least 92 octane fuel - I run 94 octane. I also needed to install a TRD 160 degree thermostat. Why TRD? Try to find another 160 degree thermostat! This further reduce pinging and richened the fuel mixture.
Prior to installing the S/C, I was running a K&N FIPK air filter. I had to take it off because it made it run too lean with the S/C. I am using a TRD drop in filter now.
Under full boost the truck still will run a bit lean. To correct this, I plan to install larger fuel injectors, fuel pump and a fuel management device.
That's it - hope this helps. Check out Ebay for great pricing on superchargers now! Get really good tech advice from -

Good luck!
