ASA 5515x Configuration Question

Good Afternoon!

I am adding a core switch to my network, so I need to change ip address of my inside interface on my ASA 5515x so I do not have major configuration changes on the workstations since IP addresses are static.  

The new inside IP address will be 192.168.3.2 with a 255.255.255.0 subnet mask.  I also am setting up VLANs so I need to do some inside routing.  I want to confirm that I am using the proper commands.

Network Diagram

ASA ==>  core Switch ==> network switch  ==> Workstations

to change the IP address of the inside interface I would type:

interface GigabitEthernet0/1
 nameif inside
 security-level 100
 ip address 192.168.3.2 255.255.255.0

To do the VLAN routing
route inside 192.168.32.0 255.255.255.0 192.168.3.1
route inside 192.168.33.0 255.255.255.0 192.168.3.1
route inside 192.168.34.0 255.255.255.0 192.168.3.1
