What is the best theme / plugin combination for a testimonial site?

I'm attempting to launch a Progressive Libertarian Healthy Job Creation political campaign targeting a MI State House seat with a platform of:

1. Legalize Marijuana
2. Ban Fracking
3. Repair the Roads

Again, it's a local campaign, so these are local issues. To demonstrate support, I want to enable video and text testimonials. I'm thinking probably Facebook Comments would do the trick, but I'm not sure which theme would be best. Also, I'm not a developer, so I may need assistance.

Your feedback is appreciated.
