Looking for advice

I’m playing a game in a few days. It’s a 3k point game, 2v3. I am play the list below, my partner is play Tau, I am not sure exactly what he is bring but it is a lot of indirect fire. The guys we are going up against are two guard players (DKoK) mainly infantry with some bullgryn and a chimera, the third is a dark angels player. The terrain is VERY urban I’m talking VERY. Only street aren’t covered by houses. I was shrinking of running annihilation legion but now I am having second thoughts. Anyone care to weigh in?
