Only the source code so far (the modules in net/sched/*.c carry comments
that describe their use)

Yes. You can hand out markings per packet using firewall rules or
routes or the cls_u32 qualifier and the various queueing modules can
prioritize according to them. Actually simply prioritizing was possible
in 2.0 too - it queues per default based on the IP type-of-service field.

Yes. Was possible in 2.0 using the shaper device, in 2.1 you can do
it by applying a token bucket filter to a particular class (or using
the CBQ module)
To configure all these features you need iproute2 from
ftp.inr.ac.ru:/ip-routing
