WELCOME ABOARD!
First, you don't need all the patches. Version 4 includes everything. Second, how new is your game? If it's 2008 or newer it's already fully patched. You can check by starting up the game. In the lower right-hand corner of the load screen it should say which version it is.
And yes, if it says 1.3
out of the box, it's fully patched to 1.4.
