this is the story.
When you use the frame-relay class command you need to
enable  frame-relay traffic-shaping, which will
automatically set CIR for all *pvcs* on the interface
to 56k.
If what you want to do is only prioritize your traffic
out of the interfce, then just use the priority/custom
queuing command on the interface.

But remember, this configuration is on a per interface
bases. If you want to enable queuing on a perVC bases
then you must have a map-class and you must enable
frame-relay traffic shaping,
or you need a service policy matching for the fr-dlci
