From your configuration I suspect that you need to configure high availability on your server farm. However, you only install 1 SQL server which will be the weakest point of your server farm configuration - hence, no high availability for the overall result.
Ok, back to the question. After doing those installation, you should enable NLB for 3 WFE , configure kerberos, and start to configure the main server, following by other server.
