Order overload and what is "checkout" ?

[feathersanddown]

Hi, I need to change flow of "checkout" process. Shop have this:

 

product summary -> select a seller, select payments and transports -> payment details -> order final status.

 

I need to add seller information because shop that I'm migrating

need to allow select one seller or if none selected system assign one to order in the same page that user

select payments and transport because transport have different price when user select dispatch place in all

my country.

 

My question is if correct to modify this logic inside OrderController (have logic of "steps") inheriting from it

and changing $step and initContent() method.

 

Then how to integrating it with PS 1.5 RC1, seems to create a module and add "override/controller" folder. But if

i'm right, where to add it? as a "Checkout" module? (in $this->tab variable of module class)

 

Thanks in advance.
