The 2626 will handle 16 i/o of adat 8 i/o of analog and spdif i/o
http://www.m-audio.com/images/global/media_hqpics/Profire2626%20-back.jpgI've never used one. So I don't know if there is a limitation for what outputs can be used at one time, but I'm gonna blindly say that it should be fine.
The AIO card in the d8b can be used to get the other 8 out of the 2626 if you need a full 24 channels. and the spdif can be connected to the board via the spdif ports on the rear of the board. And if you have the breakout cable for the 2626 you can hook up the midi and set up the d8b transport to control your DAW, and If it comes with the apogee clock card you can sync the units together via word clock and live in digital bliss.
This set up should work great for you and your classes, and quite frankly put you above the curve as far as routing in and out of the digital world. Most of the "music students" that graduate from the college in my town have a hard time hooking up a mic and getting signal on an analog console much less an interface and a DAW.
