Advanced Google Analytics Tracking (cross-domain), event tracking etc

Event Tracking:
I want to track page event clicks on website that uses jquery quite a bit.
- Embedded video: track load time, if play is clicked and if so, how much is watched.
- other interactive elements clicked on the page.
- tracking each buy now button to see which is most clicked.
- customer path of clicks leading to conversion.

Goal conversion setup
- site has 4 primary outcomes as we sell tickets to an event. 1) Gold Ticket 2) Silver Ticket 3) General Ticket 4) Subscribe for updates.

Customer Path.
1) Lading page, 2) Checkout page (different url, also hosted on our server, have full access to code of this), 3) Success page (share on social network and access download) 4) Download post sharing.

You will setup the goals to track all the above and configure in a way that reporting is clear and shows clearly what visitors are clicking and what group of events lead to conversion. Such as, do most conversions watch the video etc.

I need to get the above done ASAP.

Thank you for reading through this and I look forward to your response
