How do you go about creating a web application in a Sharepoint server farm that has multiple Web front ends(identical ones for load balancing), especially if you creating it from command line? When you create it on one web server does it get automatically copied to other servers as well? Or do you have to extend the app to other servers?

As long as you play by SharePoint's rules you don't have to worry about the multiple Web front ends. SharePoint will automatically make the changes on all of them (including future ones)
BUT if you go and make modifications in IIS manager or the filesystem (could be web.config) then you have to make these modifications to all Web front ends (also the ones you'll add in the future)
So always do all your modifications through Cdentral Admin, STSADM or the object model. And always use wsp packages when adding functionality
