1. Can I customize the home page listings - I'd like to have a larger image, and also determine what custom fields I can place in the home page listing.
You can customize this. It would require some code changes via a child theme. If you know a little HTML/CSS, this shouldn't be a problem. You could also check our upcoming marketplace (
https://marketplace.appthemes.com ) for pre-made Vantage child themes that change the look and feel of Vantage. The marketplace hasn't been officially announced but products are already selling at this time. In particular, you can check out the Advantage child theme. You can also add custom fields easily with our custom form builder. Check out a video explaining the custom form builder here:

2. When a user is creating a listing, can they select multiple listing categories? The demo shows a select box as the category selector - but in my case checkboxes would be better.
Currently, an item can be listed in only one category.
3. Can one of the custom fields accept URL's eg Youtube videos?
I believe that is not possible at this time, but you can add YouTube embed code to the description area. You can see an example of that here:

4. Is the listing page fully customizable via CSS or Child-Theme eg Image borders, etc - I know I can do stuff via CSS, but I don't want my customizations to make the theme difficult to upgrade.
We encourage everyone to use child themes for customizations. While an update to theme may upset a thing or two in your child themes, we tread very carefully when adding code. You can see a tutorial on creating child themes for Vantage here:

5. When someone creates a listing, are they added to the Wordpress Users list - where I can expose member only content, send email, etc...
Users need to have an account to create a listing. By default, they would already be a part of the users list. It's easy to allow people to sign up. You simply change the registration setting in WordPress.
6. Can the paid feature listings be recurring in billing - or do they need to be created/ordered every month?
Right now, we do not have recurring or subscription pricing. When a listing expires or is about to expire, the business owner receives an email letting them know. There are plans to add recurring pricing at a later date.
I hope this answers your questions.
Cheers.
