I'm unable to ping vlans between the 4507 and the 3845. Here are the configs:

where's the trunk configuration for the 4507??
you'll need a dot1q trunk that can carry the vlans you want to communicate between the two devices.
see the following link for more info:

Sorry, I didn't include that part.
4507:
interface GigabitEthernet3/1
description LINK TO 3845
switchport access vlan 50
switchport trunk encapsulation dot1q
switchport mode trunk

Try on the 4507:
showinter gig 3/1 switchport >> Looking for what the native vlan is, should be vlan 1.
On the router try:
conf t
interface gig 0/1.1
encapsulation dot1Q 1 native
Then try pinging from 4507 to the following ip addresses:
10.4.61.2
10.4.57.2
These are the only two interfaces that you should be above to ping since you do not have vlan 51 on 4507.
