How to setup ecommerce tracking in Google Analytics if ecommerce platform is setup on subdomain?

Yes. While Experiments reporting is session based, a user is kept into the test, seeing the same variation the whole time, so when they convert, they will be attributed to the test variation they have been seeing. This is limited to the same browser on the same device, so if the user changes devices (20% of the time for average eCommerce sites by my estimation) or clears cookies (1%) or changes browsers on the the same device (?), than Experiments (and nothing else legal) can track them. Hope this helps. PS(I suggest you look at other tools, as Experiments is the last tool I would recommend right now).

Being a Google Partner has many benefits, but they revise them all the time. Google seems to protect their intellectual property heavy, so as a partner, you can display their partnership logo to your potential clients. Also, when they roll out new products in beta, you know before the public does. As Google products go, that's a huge benefit. They provide enhanced support when you need it as well. I also do a lot of public speaking, so the one benefit public speakers enjoy is that they let you speak at their events; a very valuable benefit to us public speakers ;) I hope this answers the question.

Yes, it will track. They're pretty good at parsing partial data. The more you provide, the better you can slice the data later but anything pretty much goes in.

Do you have any interest in maintaining the domain? Is it getting regular traffic? To maintain that, you'll want to get some relevant content on the domain as quickly as possible. From there, you can decide what you want to do with it. If you just bought it for nostalgia or because it belonged to your competitor, and have no intention of doing something it with, you can do a redirect as the Google rank really won't benefit you.

I've done a lot of complex analytics installations, usually cross-domain and including AdWords and manual tagging with conversion tracking of ecommerce transactions. The gclid by default will override the manual UTM values in Analytics so that is what you are looking for. If you are just grabbing the manual tags from the URL for your own purpose, this should be OK. However, if you at some point want to import conversions (say) connected to your manual tag, then you would want to enable UTM overriding the gclid: https://support.google.com/analytics/answer/1033981?hl=en. Do you have AdWords and Analytics accounts linked? Where and how are you tracking commerce conversions, if you are? Do you feel you are getting the insights you need from your current custom reporting? Let me know if I can help with a call about those or further optimization of your analytics capture.
