N3024 Switch Configuration

I have recently purchased a Dell N3024 switch to replace an older Cisco switch and router combination that is no longer suppported plus, I did not have access to the CLI on that equipment as it was managed by a third party vendor that no longer exists.

I need help configuring the N3024.  I understand VLANS and can set that part up but what I am struggling with is configuring the various VLANS (see attached diagram) to route to the UTM firewall located on the N3024 layer 3 switch. 

Currently, the firewall resides in a seperate VLAN by itself.  I'm not sure if this is best practice or if I would be better off changing things going forward.

Any help, examples, or recommendations would be greatly appreciated.
