I would agree with @potentialgeek. Google will only probably look intently at these metrics when theu are very different to your competitiors in the SERPs. Rather than these metrics you need to be looking at what it is you want guests to achieve on your pages. As @deadsea mentions, it might be that if your guest can be satified in one page you will get 100% bounce rate, however if you are running ecommerce templates you need multiple pages and eventually a purchase to satify.
I would also (personally - Im sure some people will disagree!) recommend not using a many templates in a test. I find it much more useful to conduct smaller tests, but many many more of them. This way you can get specific information about what guests find helpful or what increased conversion etc and then add these learnings to the next test. Complex test can run the risk over complicating the learning and present false informtion back.
