Answer 1

rollbacks will occur automatically if there is an error IN MOST CASES BUT NOT ALL

if you want to guarantee a rollback for all errors precede the begin transaction with SET XACT_ABORT ON

Best practice is to explicity catch errors with a try-catch block and take action there, including perhaps a rollback and reporting/logging the error.
