When you first launch PSCS6, it will ask if you if you want to migrate your presets from a previous version (assuming that you have been working with a previous version). You can choose to migrate your presets at that time, or you can choose to migrate them later using Edit > Presets > Migrate Presets. For those of you who want to know what Photoshop is doing under the hood when you choose to Migrate Presets, Photoshop grabs the entire Presets folder in (User) Library > Application Support > Adobe > Adobe Photoshop CS6 > Presets, and uses file extensions to organize them into buckets. This means that you can have any folder structure for your presets as long as everything is contained in the Presets folder.
In addition, you can import and export presets to distribute by selecting Edit > Presets > Export/Import Presets. You can select all or Export/Import a subset of your presets. This should make it easier to keep presets the same when working with multiple computers.
