I would recommend you configure these things on a router to check them
out. With the config you have, you'll probably get an error like this
one:
Router1(config-if)#service out all
CBWFQ : Hierarchy supported only if shaping is configured in this class
My recommendation is to get used to using the show policy-map interface
command and it will tell you the bandwidth percent and rate for the
class, once the parser accepts the config for a service policy on the
interface.

Subject: Re: question for nested service policy and bandwidth statement
I want to make sure I understand nested policies.
If I have a nested service policy with bandwidth allocations, and there
is congestion on the interface, does the child allocation percent become
a percentage of the parent allocation?
As an example, if there is congestion on f0/0, will telnet get 10% of
the 50% of tcp guaranteed bandwidth? Or, will tcp get 50Mbps and telnet
get 5Mbps?
