I am neither going to try to convince you to wait and learn how to use you camera better or pontificate on the value equation of a Leica lens. I will simply tell you that if I were in your position, and I was at one time, I would strongly encourage you to get the 3rd version Leica Summicron 35/2. Relatively reasonable price (for a Leica, $7-800 +/-) and an excellent performing and handling lens.
Good luck, and enjoy!
