Index gives us most of the plot up to the start of the World War 3 arc

Not really the start of it, its prelude is a more accurate word.

And I can't say for sure but the light novel wasn't too far past that.

The second season of the Index anime ended on April 1st, 2011. By that time New Testament volume 1 was already out (March 10th, 2011). They had plenty of material (volume 14 to 22) to make a third season and even half a 4th season.

I think Miska does confess to him at some point in the light novel

Nope, what is notewhorty regarding their relationship is that Misaka realize she loves him (she didn't actually know her feelings up to that point). The only confession in the whole series is Index's.
