I just found that CWM is in fact installed. I did not realize until just now that from the HTC bootloader I had to select recovery to access it.
I placed the SuperSU.zip on the phone and installed it via CWM, as scozzar had suggested, and the phone is now rooted (verified by two root checking apps)!
From there I installed busybox via Google Play with no hiccups.
I apologize for not trying this sooner I hope that others find success. The Inspire's a great phone, and now I've made mine even better!
