Your question is not about opencv but fourier transform.
1) "To analyze the frequency content, is it appropriate to analyze just the magnitude data" read this http://www.comm.utoronto.ca/~dkundur/course_info/signals/notes/Kundur_FourierMagPhase.pdf and read this too. IMHO answer is no phase and magnitude are important your question is z= r exp(i phi). Is r most important than phi ?
2) It will depend of what you want : use google key words steerable filters
3) image is made of real number : bacsic properties are true for 2d signal
