I don't know about any specific crew and commuter parking. The airport entrance is on the East side of the field, cargo entrance on the West side, highway on the south, and 36th street on the North. 36th has quite a few seedy and some decent hotels that might let you park, there is a Marriot on the SE corner of the field thats pretty nice off of 42nd Ave/Le Juene. Other than that staying on the west side or the south side of the airport is probably your best bet.
Also be realllyyyy careful where you park down here if your car is towed you might never find it.
