The 5.0 Reptisun flourescent is a good bulb (see
http://www.uvguide.co.uk).
Does the day light bulb look something like this:
If it does: those aren't the recommended bulbs to be used as basking lights. Instead, you could use a regular (and much cheaper) household spot light that looks like this:
I'm not sure if the blue light has any ill effects on the cham, but as I said, the spot globes are the ones that are normally recommended, and provided you don't buy reptile-branded ones, they are a lot cheaper.
The red night light is completely wrong, and you shouldn't be using it. Chams generally don't need any heat source at night when they are sleeping, and in fact they benefit from a 10F-15F degree drop in temps at night. Provided the temperatures in your house are not dipping below 60F at night, there is no reason to use heating at night for your chameleons.
The same goes for 'moonglow' or other glow lamps at night: chameleons need complete darkness to sleep in.
Finally, about the combo fixture that you mentioned: make sure it does not have any plastic or glass surrounding/shielding the UVB flourescent tube, as that will block the UVB off (even if the plastic or glass is clear), and your cham will not be able to absorb it.
