Ahhh Help with Mossy Leaf-tailed Gecko Questions Pleeease!

[HumphreyBoagart]

I just picked up a couple sub-adult/adult Mossy Leaf-tails today and was reading my @$$ off about them, and to no surprise most of it contradicts each other. Just a couple questions, hopefully someone can help. Please and thanks.
First off, I got mulch and sphagnum moss for them today at the show, and noticed on the bag it says this, just like this:

Advanced Terrarium Systems

*BARK MULCH
*PINE BARK

3lb.
(15-20 gallon tank)

EXCELLENT FOR FOREST ANIMALS
REQUIRING HIGHER HUMIDITY

I always thought and just read again that pine is toxic to all lizards, I asked the guy selling about it and he told me that the oils are extracted and it's exactly what I need. Is this true? Or is it going to kill my pricey new creatures? Also I don't know if the asterix's (sp?)(stars) beside where it says BARK MULCH and PINE BARK is just sort of a check off box identifying which one it is that was unmarked or if it's both or what. I am unsure of this because the bag of sphagnum is in the exact same bag and sphagnum is just written on it with marker.
Also I've read several contradicting things about UVB lighting. Some say you need it, some say you don't.
Any help would be greatly appreciated as I'm in a mad panic!
Thanks so much.
