Here is my 2cents and personal opinion. I use a ReptiSun 2.0, or similar other 2.0 bulb. It is for nocturnal animals, but does have small amounts of UVB which helps all reptiles process D3, which as we know in high amounts is lethal. Of course, the arguement could be made, that they are nocturnal, so don't get much exposure to the UVB... true enough, but I'm finding the more comfortable my geckos get, they do venture out into the light, so I prefer to have a "good" light for them during that time.
As for basking lights, I think it is the general concensus of this forum that Leos prefer and are healthier given belly heat, utilizing a UTH with Thermostat or Rheostat. I can honestly say from my personal experiences with my leos (which I've only had 3-4 months now), that given proper substrate/ground temperatures, they are most happy. So I'd so nix the basking light.
Again, just my opinions
