Is there any point in purchasing a lens that has a fast aperture of something like f1.4?...as normally a landscape photo would be shot at something around f/8 to f/22 to get everything in focus.

With a wide angle I doubt that you would generally need to step down to smaller than f/11.  Recommendations on my Canon 10-22mm are to stay around f/7 for good DOF and optimal sharpness

I assume that the f1.4 would only be used to achieve some good bokeh?

Low light/indoor photos for instance.  Even then my Canon doesn't open up to any more that f/3.5
