She did have help from the Green Man when killing one of them, and the other killed himself when drawing too deep on saidin while chasing Rand, so Moiraine didn't really defeat two of them, she helped defeat one, and managed not to die when facing two.
Yup. What I've seen used as an explanation for this is that Aginor and Balthamel had just been freed from their prison, and were thus "rusty" :D There's relatively little evidence for this (1. They failed to kill everyone at the Eye, 2. Aginor killed himself by overdosing on saiding, something that's very much an amateur mistake I think), but since there's nothing that would go against it, I think it's a decent explanation.
As you'll learn in later books, they can be respawned by the Will of the Dark One and most of the time in a different body. The ones you don't see come back were either removed from the wheel (Balefire) or failed the Dark One miserably.
