looking through the QoS SRND i've also applied the following per device:
3750 switches
mls qos trust dscp
priority queue-out - sends all voice tfc to queue 1
**
mls qos srr-queue output cos-map queue 1 threshold 3 5
! maps CoS 5 to queue 1 threshold 3 (voice gets all of queue 1)
mls qos srr-queue output cos-map queue 2 threshold 1 2 4
! maps CoS 2 and Cos 4 to queue 2 threshold 1
mls qos srr-queue output cos-map queue 2 threshold 2 3
! maps cos 3 to queue 2 threshold 2
mls qos srr-queue output cos-map queue 2 threshold 3 6 7
! maps cos 6 and cos 7 to queue 2 threshold 3
mls qos srr-queue output cos-map queue 3 threshold 3 0
! maps cos 0 to queue 3 threshold 3 (BE gets all of Q3)
mls qos srr-queue output cos-map queue 4 threshold 3 1
! maps cos1 to queue 4 threshold 3 (scavenger/bulk gets all of q4)

**
mls qos queue-set output 1 threshold 2 70 80 100 100
! sets q2 threshold 1 to 70% and q2 threshold 2 to 80%
mls qos queue-set output 1 threshold 4 40 100 100 100
! sets q4 threshold 1 to 40% and q4 threshold to 100%
**
int range gig 0/1 - 24
queue-set 1
! assigns int to queue-set 1 (default)
srr-queue bandwidth share 1 70 25 5
! q2 gets 70% of remaining bw; q3 gets 25 % and q4 gets 5%
srr-queue bandwidth shape 3 0 0 0
! q1 is limited to 1/3 of the total available bw
priority-queue out
!q1 is enabled as a PQ

4500 Switches
qos trust dscp
strict priority queue is transmit-queue 3
By default all queues are scheduled in a round robin manner. The third transmit queue can
be designated as an optional strict-priority queue. This can be enabled with the tx-queue 3
int command followed by the priority high sub command.
By default the DSCP-to-queue assignments are as follows:
DSCP 0-15 Queue 1
DSCP 16-31 Queue 2
DSCP 32-47 Queue 3
DSCP 48-63 Queue 4
DSCP 0 should be assigned to Q2
DSCP CS1 and DSCP AF11/AF12/AF13 should be assigned to Q1
dscp cs2 as well as AF21/AF22/AF23 should be assigned to Q4
DSCP CS3 and AF31 should be assigned to Q4
DSCP 25 should be assigned to Q4
DSCP CS4 and AF41/AF42/AF43 should be assigned to Q4
DSCP EF should be assigned to Q3
DSCP CS6 and CS7 should be assigned to Q4
