One of the product pictures shows the wool covering up the entire bottom of the fireplace - even over the flame holes it appears. Is that correct?

It looks like it actually sits in front of the gas line for the flames. But it does ignite and the colors are really pretty. One bag was more than enough. peace

I replaced the fake logs in my gas fp with tumbled lava rock. if i use this under/around the rocks will it make the flames more yellow?

I don't think think so. After my gas fireplace has been started, the wool begins to glow, similar to burning embers. It does not change the color of the flame.

Can this be used in an outside gas fire pit

Probably It holds up well in the indoor gas logs. It may rust outdoors though.

how do I use with lava rock pebbles in fireplace basket?

I had lava rocks around my gas logs on the floor. I do not use them now but have the rock wool in the ember area.
