Depending on what you are trying to accomplish the placement and on/off cycles of the bulbs will be different.
Personally I would ditch the blue bulb entirely and just use the red bulb for heat. If you want a bulb for daytime viewing purposes a fluorescent bulb is the best choice as it produces light but very little heat.
The heat bulb needs to provide heat 24 hours a day. Depending on the temperature of the room that the cage is in that might mean running the bulb at full power 24/7 or it might mean purchasing a thermostat or lamp dimmer to reduce the heat output. The most important thing is providing stable temperatures, 90 F on the hot side and 80 F on the cool side. depending on the size of the cage a single heat source might be enough, or in the case of large cages multiple heat sources might be necessary.
We really need more information on your cage setup to advise on the humidity.
We need to know:
1. What type of cage/size
2. what substrate you are using
3. what you are using to measure temperatures/humidity and where in the cage the measurements are being taken
4. The average temperature the room is
5. What type of climate you live in (desert/tropical/etc.)
6. What your current temperatures/humidity are.
