first they should have NO light at night. When keeping captive herps (or any other animals)we need to mimic nature the best we can...they don't have lights on at night 
a 60 watt light during the day is not sufficient for anything but a basking light. You need to get e repti-sun 5.0 or mercury vapor bulb. Without proper UVB rays and under or over supplementation can cause MBD (Metabolic Bone disease)
Did you and/or your husband do any research before getting this animal? They are high maintenance and not cheap to keep. Did you find a local herp vet before purchasing? there is MUCH to know about these creatures as you can tell if you have been spending anytime on this forum. I spent 3 months researching before getting my first.
As for supplements, I think Carlton would agree that we can't recommend anything until we know the age of your cham, feeding habits, etc. You said he has a dripper - have you seen him actually drink?
here are a few sites for info but please continue to ask here so we can help you get setup correctly.
