First of all, it's impossible to say if the specific temperatures are good or bad without know what species you're planning on keeping in there.

As you (hopefully) know, frogs are ectothermic animals and generally do a lot better with a thermal gradient rather than an constant overall temperature throughout the entire enclosure. So, having a cooler and hotter side is a plus (however, the specific temperatures of said gradient should be adjusted accordingly to the species which it will house).
Like you said, it's not great to have both heating and lightning coming from the same source, since you will have a problem in the winter. I would consider getting rid of the red light, and either use a ceramic heater or a UTH (mounted on a side of the tank, with a dimmer or thermostat), in addition to a ordinary light-source on a timer. This way, you'll be able to keep a constant day/night-cycle and maintain a proper thermal gradient.
