Can audio being recorded be compressed on the fly?
or are there any libraries to take a .caf file, and convert to a compressed format?

The Core Audio APIs (which is what you’ll be using to record audio) allow you to choose format, bitrate, etc. You can choose a low bitrate to keep the filesize down. In most cases with the iPhone, you’re recording voice audio, and a low bitrate is fine.
