Hi Poppy,
You have asked a lot of great questions in your post. I'll answer with my opinions as succinctly as I can - please feel free to ask me or any other Realtors to elaborate.
1: ) The 60 / 40 commission splits - I find to be absurd. When listing a property, I always pay the buyers agency half of the total commission, regardless of their company policies. Yes, I've left my own money on the table, but I truly believe it is fair and right to appropriately pay the person who brings the buyer. Agents are more likely to show my listings because they know that they will be appropriately compensated.
2: ) If you, or any of your friends are interviewing Realtors about listing property, either here or anywhere else, ask what they do to market the home. In some cases, a sign and MLS entry are sufficient. However, I don't think that anyone should count on that to be the sole marketing campaign. I personally do far more than that with each of my listings (Sowal, Walton Sun, Facebook, Pinterest, MLS Tours, paid premium placement on Trulia, etc.). Please feel free to ask for more details.

Finding an agent is easy; finding an agent who will work to sell you property and knows the area is not as easy.
