Ranking speakers – is this the right plugin?

I help maintain a website for a state non-profit Beekeeper organization. One of the things we provide is a list of speakers (and the various subjects they speak on) so that clubs within our state can call them to do presentations for their monthly meetings.

It’s just a simple list that might look something like:
Doe, John – “Beginning Beekeeping”, “How to do splits”
Lincoln, Abraham – “Maximizing honey production”, “How to treat for mites”
Jones, Sally – “Chemical Free Beekeeping”, “Top Bar hive management”, “Meade Making”

Currently we have no idea who is actually a good speaker and who isn’t. So I would like to add some functionality to this list and provide a way for people to both rate the speakers (scale of 1-5) as well as provide comments/feedback. A couple of things about this:

• I would like the ratings of a speaker to be limited to “1 per IP address”. While I would like to think nobody would use this as a personal weapon, I know that someone, somewhere probably would.
• Both the ranking and review should be done anonymously (ie. not require a logon)
• I would like the person doing the review to be ‘prompted’ to mention the name of the class, date, other details.
• The reviews would need to be approved by a site moderator. Moderator could approve after making edits to the review (ie. “moderator edited to remove foul language”).

So… is this the right plugin for what I am trying to do? If not, is there a suggestion for something else?

If it is, does someone have a website I can look at for an example?

note: I am not a programmer, so anything that requires me modifying .php code or directly modifying sql tables is out
