1) No, unfortunately. 2) Green card options aren't tied to or dependent on in any way the individual's nonimmigrant status so your possible options are the same whether you are in L-1B, H-1B, O-1, etc. It's just coincidental - not causal - that those in a certain nonimmigrant status go down a certain green card path. That being said, most of those in L-1B status go the PERM/labor certification route or the NIW route.
