Stored Procedure with IF Then Statement

The code for my sp shown below works so far.  I need to add some other elements.
1.  I need an IF Then to insert into a third table.  The variable is the EventType that I am sending in.  I have never done this before and I am not sure how its formated and where it goes (between current Begin End?)
2.  I need to write the scope identity from the Person and SafetyEvent tables to this third table.
3. I need to return the scope identity from the Saftey Event table to my applicaiton.  Note that this is working in the current code.

CREATE PROCEDURE spInsertEvent
 
	@Name		             VARCHAR(50),
	@DOB			DATETIME,
	@Status 		VARCHAR(10),
	@AcctNbr 		VARCHAR(15),
	@AdmitDate 		DATETIME,
	@Location		VARCHAR(50), 
	@Unit			VARCHAR(15), 
	@Fac			VARCHAR(50),  
	@PType		VARCHAR(20),  
 	@EventType		VARCHAR(50),
	@ReportedBy		VARCHAR(50),
	@EventDate		DATETIME,
	@EventTime		VARCHAR(5),
	@EventLocation	VARCHAR(50),

	@ReporterPhone	VARCHAR(15),
	@ReporterDept	             VARCHAR(50),

	@Description		VARCHAR(500)
