Very interested in the Delta 66.....I can't find much info on the breakout box though - can I plug my headphones into it?
You can't plug headphones into the delta 66:
"The M-Audio DELTA 66 PCI Digital Recording Interface. 6 Input / 6 Output PCI Sound Card with Breakout Box for Mac and PC.
The M-Audio DELTA 66 was designed for the person requiring an audio card with professional features and performance, but with a price tag well below that of typical pro gear. The Delta 66 boasts an incredible sounding converter section with 24 bit 96kHz operation. Its S/PDIF I/O makes it possible to perform digital transfers in and out of the system, useful in mastering to DAT or utilizing outboard FX via digital I/O. The breakout box handles four balanced or unbalanced, +4dB or -10dB signal level analog inputs and outputs. Also included is the Delta control panel software which configures the card and controls digital mixing, routing, and even SCMS (Serial Copy Management System) output on S/PDIF.

Edit -anybody here using it with Vista64? Any problems etc.?
They haven't released 64 bit drivers yet. Edinho must have got a little excited. They have started a beta testing program and the beta is not for general download yet.
