I should be able to share with you the outcome of this assembly... Once all is done!
good luck, what I am in the process of doing:
1) 5/8 fire rated - 2 layers with green glue between and GG noise sealant around
2) resilient channel though I went 16 oc even though the joists are 16 oc, your method is good
3) screws to make it through and grab the channel are all thats really needed.
4) I went with the denim insulation since it was on sale and I am always willing to try new things.
I did find a good spec sheet for guidelines on resilient channel, maybe it will help you as well.
I'm a little over half done and very happy so far. I have my work office in the basement and what I hear for voices above me now only come through the unfinished area. the extra mass also helps to deaden the clomping that we all know kids are great at too.
