Those first lines are installed by the Fedora version of
jack-audio-connection-kit. There should be jackuser group
in /etc/groups, otherwise it is a bug I guess (in Fedora's jack
package). I have to add my own stuff there because the priority they
chose is too low for the realtime kernel and rtirq and because I enable
all users to use rt (so that anyone can lock the machine). I used to do
this with an upgrade to pam (no longer needed). 

The more open lines (the ones starting with "*") should have priority so
you can leave the others undisturbed...

Let us know how it works out for you...
