ecommerce canada post

I'm struggling to get Canada Post shipping to work in eCommerce 3.5. I want to collate a page that includes all of the necessary steps to fix it. So far, I've applied some patches, and gotten past a configuration error, but no shipping methods appear in the "Choose shipping method" page during checkout.

Here's what I've done so far.

1) Applied the patch from http://drupal.org/node/143328#comment-554073.

2) Applied the patch from http://drupal.org/node/201042#comment-827422.

3) Put dimension and weight settings on my product.
