Appreciate the help, but I think I am still unsure of that last point.
If the default policy for INPUT is DROP, and a rule "allowing" traffic
is not matched, once it gets to the end it performs the default policy
action from what I have gathered now.

This contradicts the suggestion you make about it jumping to the next chain?
Are you sure (it was an RH instructor today that explained this to me)?
