I ended up solving my problem, but not in the way I wanted. Since my phone was 100% dead, I went back to ATT since it was still under warranty. I told them a story about how the phone had been malfunctioning lately and then just completely died. They replaced the phone under warranty, so now I have a brand new one.
There definitely doesn't seem to be any easy way out of this problem once it strikes. I still don't know what happened to make the phone unable to boot out of recovery, even after wiping stuff, factory reseting, and reflashing roms. All I do know is that I have never had a problem with PhilZ until I started to rapidly tap the blank part of the screen (I like how it vibrates... I'm weird like that). This caused the recovery to never want to exit. Every time I reboot the phone, it automatically went to recovery, even after a full power off or battery pull.
Nevertheless, I am still going to root and mod my phone... just carefully.
