It's easier to maintain humidity without a basking light, so a lot of folks use fluorescent or other "cool" sources for viewing light and use heat tape or mats, flexible heat rope, ceramic heat emitters, or even radiant heat panels for large snake enclosures.
Basking lights are better for heliotherms like iguanid and agamid lizards that depend on UV and IR light for thermoregulation.
I've never built my own cage so I'll leave the more specific questions to those with more experience, but I love wrapping flexible heat rope around two sides of the bottom of a snake enclosure for heating. You can plug it into a thermostat to control temps beautifully.
