Fixing checkout workflow issue

FYI, this is the checkout workflow right now:

coupon_cart_fields,login_address,shipping_payment_confirm,end

The above brings me to the shopping cart and asks for a coupon code.
It then takes me to the address collection.
It then takes me to the payment and shipping selection
Finally it sends me to PayPal

I want to change it so that:

Brings me to the shopping cart and asks for a coupon code.
Takes me to address collection
Takes me to the payment and shipping selection
Shows me the final totals (cart with shipping and tax)
Finally sends me to paypal.

How do I adjust the checkout workflow for this?
