What is the most effective way to write Statement to catch and reverse errors during query excution?

Question

Hello my friends:
I am wondering what is the most effective way to deal with errors, specifically in a
Stored Procedure.
I wrote something like this:
BEGIN TRY
BEGIN TRANSACTION
/*My statements goes in here*/
IF ERROR_NUMBER() = 0 -- Do I need this line?
COMMIT TRANSACTION;
END TRY
BEGIN CATCH
IF ERROR_NUMBER() > 0 --Do I need this line?
ROLLBACK TRANSACTION;
END CATCH;
It would make sense using the if Statement when attempting to log errors.
Just too many variations.
Thanks
