Hi John,
Is your Gram input on a phono socket? If so, it's possible you're not using the right sort of phono plug; the older ones had a much longer centre pin, and the modern ones don't reach the right part of the socket...
Don't worry about level or impedance at this stage; you should easily get enough signal from the headphone socket of an MP3 player to get a reasonable signal. The faint noise you get might indicate that you're only getting capacitive coupling from a plug that isn't quite reaching the socket...
