This is my own unique experience with Google Checkout. You may or may not be having the same issues and came up with the same solutions as me, but in the event that you are stuck, this is what I have learned.

1. The only checkout option I give my customers is Google Checkout. I removed the normal Checkout option because too many customers found it confusing that if they clicked the normal checkout button they couldn't then checkout through Google. Of course, Google is the only credit card processing service I offer and it works well for me. I have been strictly using Google Checkout for a month now and so far no problems. Since Google Checkout isn't charging any fees until 2008, this is also the most cost effective solution for me.

2. The shipping integration has just never seemed to work right, therefore, I decided to just charge a flat shipping fee and flat handling fee per item. I disabled all other shipping options including Free Shipping and this seems to work. I would like to, at some point, integrate with USPS and have it calculate correctly in Google Checkout, but right now it just doesn't seem to work right.

3. I've never had any problems with my sales tax. They seem to calculate correctly in Google Checkout. I do not like, however, how Google adds the sales tax to the price of the item and then in small font says THIS INCLUDES 8.25% SALES TAX. I think the Sales Tax should be a separate line item like Shipping and Handling.

4. I also wish that I didn't have to enter my coupon codes separatley in Google Checkout. This means if I want to offer a new coupon, I have to add it in Zen Cart and then add it in Google Checkout. Seems like my customers could just enter it before Checkout and it pass through to Google Checkout.

Don't know if this info will come in handy to anyone, but if you have a question, feel free to email me using the form on my site.
