>1. Do i need to assign ips in all interface of  Primary firewall and Standby firewall ?
Yes. With 7.x you cannot use 127.0.0.x or un-assigned

>2. What are the configuration which we need to do it in Standby firewall ?
Nothing. All configuration is done on Primary only

>3. How do i upgrade OS on a failover mode PIX ?
Use this procedure:

>When do i need to connect this failover and stateful failover cable between Primary and Standby firewall?  
Connnect the serial failover cable before you power on the standby unit. Connect the stateful whenever you want.

> this is to be done after all configuration done in Primary pix ?
Does not matter

>initially how do i replicate the current configuration to Standby firewall?
Enable failover, then write standby
One simple command on Primary:
  failover
  write standby

>what is the host name i need to give it in Standby mode?
Does not matter. When a failover occurs it has same name as Primary.
