Answer 1

What you are probably going to have to do for this is set up some sort of case in JS where it checks the fields validity before moving to the next tab (this is quick pseudocode)

on click for next step

if ( all fields are valid )
    go to next tab like normal
else if 
    .focus on field that is not complete
