This may be a obvious answer but one of our current projects uses 4 relays with a 360ma rating on the coil, 2-4 20ma LEDs, a PIC, a MAX232, and some other minor components. Should I provide a power supply for the total current needs or could I get away with less? My main concern is the relays. I would like to make sure they can all be on at the same time if needed.

I guess I didn't read enough into it. Thanks for the help! Also, am I reading it right that even though it states 6v for the coil, it would pickup at only 4.2v?
Yes, but remember the Pick Up and Drop Out voltages are approximations and shouldn't really be counted on. Meaning if you have a 6 volt relay coil it "should" pull in at 4.2 and should drop out at .6 volts but don't design or build around those numbers.
