Probably none for or against (though some complicated investigations of the 
isotope ratios in the fossils could help -- if diagenesis hasn't destroyed 
all information over that long time...).

Zero.

(Which giant spider? I hope it's not *Megarachne* the short-tailed 
eurypterid???)

Sounds very, very unlikely. Some birds, however, do that kind of thing.

Some do, some don't. Tigers for example.

Komodo monitors live in trees when they are still small.

Interesting. I don't know that fish.
