Hi Rob,
Let’s see if I can get your questions answered for you. Even though you are located in the UK, you CAN sell Buy Shield warranties to customers who are located in the US. However, Buy Shield warranties cannot be purchased by buyers who are not located within the US. As with all sellers, you must adhere to all tax requirements of someone who is doing business in the United States.
Since you are located in the UK, after amassing $600 in revenue through Buy Shield's revenue share program, you would have to fill out the necessary paperwork to comply with US tax codes. The following links provide some useful information on this specific topic:

The "Meet all conditions for payment" requirement you are referring to is just intended to indicate that you must comply with all of the other specific guidelines mentioned in the terms of service, such as complying with US tax codes as described above.
The part of the terms of service that says "You agree to indemnify and hold Buy Shield harmless from any and all third party claims" statement is essentially meant to indicate that, by using Buy Shield, you are agreeing that we cannot be held responsible for issues arising from a misrepresentation of our product on your auctions or website or a failure to comply with applicable laws pertaining to the sale of Service Contracts and consumer electronics.
For example, if a seller were to misrepresent a consumer electronics item he/she sold and the buyer of the item was to file a Buy Shield warranty claim after the item broke, it is possible that the claim could be denied on the basis that the seller violated the law by misrepresenting the item. If the buyer were to sue the seller as a result of this situation, the seller would not be able to hold Buy Shield accountable.
We will be working on improving our FAQ as the product expands and we get a better idea of what the most frequently asked questions really are. Also, while we do have several employees that peruse our community forum with the intention of assisting customers, the primary purpose of our community forum is to provide a resource where Auctiva members can assist other Auctiva members.
In the event that you need to receive assistance from a customer support representative regarding the Buy Shield service, I recommend calling the 800 number listed on the following page of the Buy Shield site: http://www.buyshield.com/Support.aspx
