cisco

I'm very new in networking and I'm trying to setup my network as follow

[ISP Modem/Router/Switch] + --- + {fxp0} [Linux Firewall] {fxp1} + --- + {??} [Cisco Router 1921] 
{GE 0/0} + --- + [Cisco Switch] + ... Servers
{GE 0/1} + --- + [Cisco Switch] + ... Servers

My questions are,

Since I'm using both GE 0/0 and GE 0/1 ports to connect to switch, how can I connect my Linux Firewall (Port fxp1) to my Cisco Router?
I know the USB and Console port are for configuration, can I use AUX port to connect my firewall (if so is it consider a right way)?
Is my setup is right? if not can someone please explain to me to do the setup in right way.

Link to the picture of my router: Cisco Router 1921

Thanks
