It is. I've seen on the youtubes.

Random. I'd try to find one good tree and take the saplings.

As for Diamond, it does not spawn near lava simply because of the lava.
Diamonds spawns in 0.0846% of blocks from level 2-16. Most commonly around layer 9. Lava spawns on levels 1-10. It just so happens you can find diamond in those locations more easily due to the open a lit up nature of them, and it is a good idea to look for them there just in case. But you can find diamond behind even a block of dirt, far away from any lava sources.
