For awhile I was collecting links to clients of Dons that use the small biz theme that ranked in the A spot. When I was doing research for other clients, I would sometimes find them at the top of the pack. Can't find the list now, but there is a ton of info on his site.
A local SEO theme as opposed to a general SEO theme will do a good job of local NAP schema etc. but I'm sure Yoast's plug-in also does a good job. I just don't know if he "lives" local like Don does, but I've heard good things about it.
