My point and also you have best people around the world to provide you better answer:-
I have a setup that will require routing between 3 Vlans and have multicast contained within one of those vlans across 4 switches.
For controlling the mcast vlan I will enable IGMP Querier on the vlan on one switch and IGMP snooping on all the rest, or do I have to enable querier on each that has the Multicast VLAN? I do not want to use PIM.
Answer:- No you dont need to enable PIM. IGMP querier to be enabled on only one switch.
(Some good info:-http://www.cisco.com/c/en/us/support/docs/switches/catalyst-6500-series-switches/68131-cat-multicast-prob.html#solu2)
To clarify:
VLAN101
VLAN102
VLAN103 - Multicast on this vlan using IGMP Querier and Snooping
Would the 2960-XR be capable of this or would I need to upgrade to a 3650 for routing between the vlans?
Answer:- If you already have 2960 then this will do the job for you.

You need to change the SDM template on the 2960 to have this configured.
