Hi Alexia,
you can animate the camera by setting animation keys for the camera's position and rotation.
However, moving the camera in the 3D preview doesn't really change the camera's parameters UNLESS you hit "set camera" (with the button below the 3D preview). Once you hit "set camera", you can then set the animation keys (position and rotation) in the camera's node dialog.
There is no frame rate as such, TG2 will just output the number of images in your animation that you have specified. What you would do is set the camera e.g. for frame number 0, the move the camera to the next position, and make this position i.e. frame number 25, then hit set camera again, then set an animation key.. You'll need to compile these to a movie, and set your frame rate then. So considering these 25 frames, you can have a 1 second animation at 25 fps, or half a second for fps 50, ....
cheers,
Frank
PS: I'm no way near experienced or anything in animation, there are many others here who could tell you more about this. But in essence, the above mentioned steps should work.
