hmm my understanding was that Kickstarter kit was a "hey see what it can do once fully configured!" example of Commerce. Understanding the setup -- you could then go back and install/configure Commerce by hands to your needs.
That being said Commerce content I think is just Entities and Nodes, If you want an non-SQL way to reset a site (i've written ~34 sql Delete statements to nuke content from sites in an sql script for drupal -- it's not that hard you just look at
field_* tables mostly when clearing
content from a drupal site) I'd recommend looking at the Delete All module and the documentation found in
drush help delete-all as a GUI means of selecting out types of content to nuke from a drupal site.
EDIT: DrupalCamp Montreal 2014 steps to setting up Commerce ala Commerce Kickstart but Not Depending on the Kickstarter kit

Step by step guide to installing Commerce from scratch
The following guide was used in a presentation at DrupalCamp Montreal 2014.
The presentation focused on how to install Drupal Commerce from scratch
(i.e. we won't use the Commerce Kickstart distribution).
This is an elevator guide. So get in now because we're going up!
Install required modules
drush dl ctools views entity rules addressfield commerce
drush en ctools views entity rules addressfield commerce -y
use the provided drush commands
drush en commerce commerce_ui -y
drush en commerce_customer commerce_customer_ui -y
drush en commerce_price -y
drush en commerce_line_item commerce_line_item_ui -y
drush en commerce_order commerce_order_ui -y
drush en commerce_checkout commerce_payment commerce_product -y
drush en commerce_cart commerce_product_pricing -y
drush en commerce_product_ui -y
drush en commerce_tax_ui -y
Add a few more useful modules
drush dl admin_menu module_filter zurb-foundation-7.x-4.x-dev jquery_update -y
drush pm-disable toolbar
drush en admin_menu_toolbar module_filter jquery_update -y
Create a responsive Zurb subtheme
drush fst Your Subtheme Name your_subtheme_name 'A subtheme of ZURB Foundation.'
Set jQuery update to 1.7+ (admin/config/development/jquery_update)
Enable your new responsive subtheme (admin/appearance)
Quick tour of what we've got soo far
1 Product type named 'Product'
2 tax types
LOTS of hidden functionnalities
NO visible products
and NO, you don't get a store out-of-the-box
Commerce Kickstart gives you that but you won't know how to get there if you don't try from scratch
Create a new product type 'Download'
add file & image fields
Revisit 'Product', the product type installed by Commerce
add an image field
Let's create products
a physical product (Product)
a virtual product (Download)
Now what? where's the store?
Out-of-the-box Store is for wimps! ; )
Commerce products only exist in the backstore
products are like brown boxes in a warehouse: they're only accessible to the store's employees
in order to make products accessible to customers, you need to put them on display in a nice and attractive way
how do we do that in Drupal?
we use content types, of course
Create a content type for displaying products
how does Commerce differentiate & recognize product displays from regular content types?
a product reference field!
create product displays and configure them
Alright, let's shop!
wait a minute, nothing happens when i click Add to cart!
In case you didn't read the fine print: some assembly is required, like Ikea, but without the KISS diagrams
Introducing Rules... doh! where's the UI ?
drush en rules_admin -y
go to admin/config/workflow/rules and add a rule that redirects to the cart
Welcome to the cart
Time to checkout wouldn't you say ?
doh!... something isn't right
where are the taxes?
Like I said, Out-of-the-box taxes are for wimps! ; )
Commerce's taxe model is simple
there are tax types; like there are product types and content types
and then there are tax rates which you create using one of the available tax types
Create GST & PST tax rates (note - these taxes are specific to the Province of Quebec in Canada where the camp was held)
Revisit the checkout
Darn, the taxes are not displayed in the expected order! (i.e. GST on this first row, PST on the second row)
How do we change the order in which taxes are displayed ?
the hard way: by overriding theme_commerce_price_formatted_components() in the theme's template.php (see https://drupal.org/node/1095576#comment-8721217)
the easy way: by creating separate tax types for GST and PST and playing with their respective weight (note that at the time of this writing, the behaviour for tax weights does not follow the convention where lighter weights float to the top; see this issue)
Are we in business yet? Not quite.
Setting up a payment method
for simple tests, use the 'Example payment' module (provided by Commerce)
For serious tests and real sales, you can use Stripe or Paypal or whatever works for you. For the purpose of this presentation,I used Stripe.
setup an account
get the API keys (secret and publishable)
Install & configure Stripe
drush dl commerce_stripe
drush en commerce_stripe -y
add both keys to the Stripe payment method rule (admin/commerce/config/payment-methods/manage/commerce_payment_commerce_stripe)
Time for some tests
for this, we use the dummy credit cards provided by Stripe
When you're happy that all works like it should you can replace de test API keys by the live API keys.
