Creating a database who is the owner?

Hi there
I running into some serious problems trying to get a new database created then running a script to created the tables, relationships, indexes and insert default data. All this I'm making happen during the installation of my Windows application. In most cases I'm installing SQL 2012 Express as a prerequisite of my application and then opening a connection to that installed SQL Server using Windows Authentication. eg:Data Source=ComputerName\SQLEXPRESS;Initial Catalog=master;Integrated Security=SSPI; Then I run a query from my code to create the database eg: "CREATE DATABASE [MyDatabaseName]".
From this point I run a script using a Batch file containing "SQLCMD....... Myscriptname.sql". In my script I have my tables being created using "Use [MyDatabaseName]   Go   CREATE TABLE [dbo].[MyTableName] .....". So question is, should I have [dbo]. as part of my Create Table T-SQL commands? ...
