I would like to start putting theory to practice using my board but I need an expansion board of some kind that can allow me to do these things. I've researched some options and have come up with two. However, I'm not for sure what the major difference is between them and which one would be more suited to my needs.

Actually, you're better off starting in the "perfect" digital world. You digital signal processing can consist of;
1. Create an input signal, eg., in MATLAB.
2. Download the signal to RAM.
3. Processing that signal with your DSP logic and write the output to RAM.
4. Read the results RAM, and check in relative to your MATLAB code.
There's some example documentation and links here:
https://www.ovro.caltech.edu/~dwh/correlator/cobra_docs.html Look at the JPL and EELive slides, the FFT tutorial, and the ESC-104 slides, paper, and example code.
That'll give you some ideas, and you can start with the hardware you've already got.
