is it just a matter of setting the appropriate pins on the expansion headers as inputs/ouputs, or am I overly simplifying things.

That is pretty much all you have to do.
Of course you do have to get the pin assignments right, and you do have to avoid violating the voltage specifications of the pins.
There are several DE2 varieties. The DE2 has a Cyclone II device and a couple of 100-mil expansion headers. The DE2-70 Cyclone III also has these headers. The DE2-115 has a Cyclone IV, and it has one header and an HSMC connector.
You need to look at the schematic for your board, and generate the pin assignments from that. Take care that the schematic is for the exact revision of hardware you have.
