It seems that the MAX11300 has current limiting resistors baked in. How much extra circuitry did you add to the outputs for further protection and would I need more circuit protection for inputs?

I've just added 2x 50 Ohm resistors and a 10 nF capacitor.
Inputs should probably work with the same circuit, as everything can be configured in software. So you can configure the port as input/output and also set the range (-5V to 5V or 0V to 10V).
Not sure what happens when you configure a port as a -5V to 5V input, and then plug in a 10V signal.
