Answer 1

You haven't said what error you are getting, but you should have quotes - curly or otherwise - within your case expression. Instead of:
PHONE "CASE WHEN SUBSTR(:PHONE,1,2) = '1-' THEN ‘SUBSTR(:PHONE,3)’ ELSE ‘:PHONE’ END",
use:
PHONE "CASE WHEN SUBSTR(:PHONE,1,2) = '1-' THEN SUBSTR(:PHONE,3) ELSE :PHONE END",

Answer 2

You could also just keep the last 12:
PHONE "SUBSTR(:PHONE, -12, 12)",
