Kevin,
1. Here is a link to the links section, there might be something in there to help you out.

2. In my opinion, a clip is the best option because you get everything you will need for the swap with a clip. Most people spend more money putting their own kit together and usually takes twice as long to acquire everything.
3. There have been a few cases of the 3S catching on fire. I personally believe this is a rare case that can happen with any car. A fuel leak, hose too close to a heat source, lightning strikes....etc.
4. Full clips can be found at different places.....
