How can a lost SA password be reset on SQL Server

I've been handed a SQL Server 2008 to maintain.  The previous admin has "lost" the SA password.  No other accounts on the database server have SA privilages.  I want to gain SA access to the database server.  I've read but never done the following:
1. Stop the sql server services.
2. Start the sql server instance in single-user mode:  SQLServr.exe -m
3. Connect to the instance:  SQLCMD -S <Server_Name\Instance_Name>
4.  Create a login: 1> CREATE LOGIN 'Login_Name>' with PASSWORD='<Password>'
                                 2> GO
5. Give the user SA rights:  SP_ADDSRVROLEMEMBER '<Login_Name>','SYSADMIN'
6. Stop the sql server services.
7.  Restart normally.

Is this the correct procedure?  Any suggestions?

There is one production database on this server.  The transaction log is about 36GM and the database is about 600MB.
I will tackle that once I gain SA rights.

That seems correct, you need to make sure that the you start the command prompt as administrator and run the statements 2 and 3.

No, is not correct at all. if it was that easy what kind of security SQL Server is offering to us?
If you lost the SA password and no one more has SysAdmin permission on the instance you can try to connect with the SQL Server account (if it is a domain account) otherwise you can't do nothing but reinstall the SQL Server.

You may want to double check that.

I was able to stop the SQL Server and restart it in single user mode using: NET START MSSQL$<instancename> /m

I was able to use Sqlcmd -S <Server_Name\Instance_Name>

Then I tried this to create a user and assign sysadmin to it.
1>      CREATE LOGIN ‘Jack’ with PASSWORD= ‘*********’
2>      GO

1>      SP_ADDSRVROLEMEMBER ‘Jack’,’SYSADMIN’
2>      GO

But the user was not created.
How do I fix this one.

This
CREATE LOGIN ‘Jack’ with PASSWORD= ‘*********’

Would have caused the following error:
Msg 102, Level 15, State 1, Line 1
Incorrect syntax near 'Jack'.

The syntax to create a  Login (not a User) is as follows:
CREATE LOGIN Jack with PASSWORD= ‘YourPasswordGoesHere’

Thanks.  But now I cannot connect using Sqlcmd -S <Server_Name\Instance_Name>
I am at a loss to figure out why.

I was finally able to connect and create a user and give that user sysadmin rights.

Used this:
CREATE LOGIN [Jack2] WITH PASSWORD=N'********', DEFAULT_DATABASE=[master], CHECK_EXPIRATION=OFF, CHECK_POLICY=OFF
GO
EXEC master..sp_addsrvrolemember @loginame = N'Jack2', @rolename = N'sysadmin'
GO
