Hello Jacob,
Stephanie is correct, all the Cisco Small Business emulators are available here:
https://supportforums.cisco.com/community/911/cisco-small-business-online-device-emulators
There isn't an emulator for the 500 specifically, except for a very out of date CLI emulator that I don't recommend using. The 300 series emulator is very similar, since they share most of the same features so you can take a look at that to get a feel for.
However, those emulators are also a few firmware versions back, so not all of the new features are listed in the emulator (a big one being the DHCP server we added to the layer 3 switches, along with a few minor GUI changes and lots of little feature additions) but it will give you a good idea of what to expect from the interface.
I would also recommend looking over the Datasheet and the Admin Guide for the 500s, they are updated more frequently (usually with every firmware version) and do contain the new features.
As for the 2960 there aren't any emulators available as far as I know, IOS is a bit more complicated to emulate, however there is a huge amount of documentation on IOS configuration and it tends to be the same for most Catalysts, so just Google what you are looking for and Cisco will probably have documentation and excellent examples of the commands available on the Catalysts. Just keep in mind the Small Business switches do not use IOS, so don't necessarily have the same features, but a lot of the CLI commands are the same, or very similar.
Hope that helps and thank you for choosing Cisco,
