...and handicap applications?It's been awhile, but according a quick perusal of 210 of the 2008 NEC, the only place where I see a height requirement for a general purpose receptacle is in a kitchen (<20" from top of counter), and outdoors (<6.5' from grade or deck). Also in regards to spacing, generally speaking, no section of wall over 2' can be more than 6' away from a receptacle. There used to be a little formula for determing how many receptacles are permitted on a general purpose 15 or 20A circuit, but it's been too long for me to remember and I'm not able to spot it in my code book right now.
