I've been doing it this way for 13 years:

GFI's - strip the line wires if the GFI is protecting more receptacles
3-way switches - strip the common, and always try to use black for common
Single pole switch with 3-wire going out to device - we always use red for switched line and black for steady hot
4-way - in and out twisted separate
Ganged boxes - wires twisted together and rolled into position they will go
Very seldom do we use tape
