I dunno. Liara doesn't seem like the jealous type, and asari may view relationships differently from humans. No telling.

On the second point: I'm no expert in logistics, but based on what we know about quarian spirituality, I'd guess "Keelah" means "ancestors." Saying "keelah" by itself is like someone saying "God": it serves as a statement of exasperation, shock, frustration, etc. "Keelah se'lai" is almost certainly a blessing, maybe something along the line of "ancestors be with us."
