Programming language no... we usually don't have access to the code as this is super guarded by the clients. It does help to uderstand the process through which the product is being built... helps but it's not necessary. Specific tools... yes, do do make use of all kinds of tools. Sometimes the client helps with using simulators or the device, so I would say you have to have the willingness to learn something technical. The actual learning we can teach, or the client can teach... it's the willingness from you that helps.
