Thanks for the advice, but don't hate me if I don't heed it. My roommates and I are all electrical engineering students and we love to make things work. I'll bring up your suggestion next time we discuss it but we're probably going to move forward anyways. I've already gotten most of the hardware we will need- NIC's and whatnot- and we realized that if we want the NAS and the router to be in the same machine then pfsense wouldn't be able to do everything. If we can't get it working and frustration makes us stop then at least we will have the experience and the extra hardware.
