Software Deployment

I need to run some sql and dot net commands as part of an installation such as the following:

SQL commands:

IF NOT EXISTS (SELECT * FROM master.dbo.syslogins WHERE loginname = someUser')
CREATE LOGIN [someuser] WITH PASSWORD = 'somepassword'
GO

/*specify the database*/
USE [local]
GO

/*create new database role*/
CREATE ROLE db_executor
GO

/*grant execute to the role*/
GRANT EXECUTE TO db_executor
GO

/*Create User*/
CREATE USER [LocalSQLUser] FOR LOGIN [LocalSQLUser] WITH DEFAULT_SCHEMA=[dbo]
GRANT CONNECT TO [LocalSQLUser]
GO


Dot net commands:


ren "C:\Program Files\Application\Mobile.exe.config" "web.config"

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis -pef "connectionStrings" "C:\Program Files\application"
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis -pef "appSettings" "C:\Program Files\application"
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis -pef "system.net/mailSettings/smtp" "C:\Program Files\application"

ren "C:\Program Files\application\web.config" "Mobile.exe.config"



ren "C:\Program Files\application\DBSync.exe.config" "web.config"

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis -pef "applicationSettings/DBSync.Properties.Settings" "C:\Program Files\application"

ren "C:\Program Files\application\web.config" "DBSync.exe.config"


What I need to know is if all this stuff would go into the CustomAction table or if there is another method for running these types of commands. Should they go in batch files that get deployed and run using custom actions or stored in the custom action itself if even possible? Why I ask is because my only tools are Orca and InstEdit. Thanks to the members here I know how to add VBscript custom actions but I'm not sure about the above commands.
