Is there an easy way to grab domestic shipping rates overriding the default destination address?

To achieve your objective, you will have to use the func_get_shipping_methods_list function. The function returns a PHP array.

In your case, the key setting is $config['General']['apply_default_country']. The 'Override destination address before shipping calculated' task is implemented here:

[~/www/xcart_4_4_x]$ grep -r --include='*.php' "apply_default_country.*Y" *|grep -v '=='|grep -v '!='
modules/Amazon_Checkout/func.php: $config['General']['apply_default_country'] = 'Y';
modules/Google_Checkout/gcheckout_callback.php: $config['General']['apply_default_country'] = 'Y';

Here is the code from modules/Amazon_Checkout/func.php

function func_amazon_get_shipping_methods12($cart)
{
...
  // Option adjustment to avoid empty($userinfo) checking
  // $userinfo will be provided by Amazon in callback
  $config['Shipping']['enable_all_shippings'] = 'Y';
  $userinfo = $cart['userinfo'];
  $products = func_products_in_cart($cart, (!empty($user_account['membershipid']) ? $user_account['membershipid'] : ''));

  $_need_shipping = func_cart_is_need_shipping($cart, $products, $userinfo, 'dont_check_free_ship_coupons');

  if (empty($_need_shipping)) {
    $result_cache[$md5_args] = false;
  return false;
}

// Some options require adjustment
$config['Shipping']['enable_all_shippings'] = 'N';

// Emulate the 'apply_default_country' option enabled
$config['General']['apply_default_country'] = 'Y';
$config['General']['default_country'] = $userinfo['b_country'];
$config['General']['default_zipcode'] = $userinfo['b_zipcode'];
$config['General']['default_state'] = $userinfo['b_state'];
$config['General']['default_city'] = $userinfo['b_city'];

$intershipper_recalc = 'Y';

x_load('shipping');
// Get list of all shipping methods that are potentially available for customers
$shipping_methods = func_get_shipping_methods_list($cart, $products, $userinfo);
...
}

Adjust $userinfo['b_*'] according to your warehouse address

Or use the code from modules/Google_Checkout/gcheckout_callback.php

If I wanted to grab the coupon codes being used on a specific order, where should I be looking? Is this included in the $cart data?

This variable stores the coupon code applied to the cart after cart recalculation:

$cart['coupon']

The same field is available in the sql xcart_orders table.
