I am configuring QOS for some 2960-X's for a new deployment that also has some 2960's. The current 2960's already have auto qos configured. When I configured auto qos voip trust for the 2960-X, I noticed there were not any ingress queues and the all of the numbers for the queues were different. Should this be a concern at all if the switches are trunked together or even if they aren't? I am not that proficient with QOS yet. See below for configs.

IMO, AutoQoS is always a concern (as are device defaults, without it).
If you're doing to "do" QoS, you should have a policy that serves your service needs, and configurations to support it. AutoQoS might, or might not, be exactly what you need.
If you're not proficient with QoS, on most LANs, you might actually be better off disabling it.
