Rockyboy; here's a simple chart showing approximate gain needed for a range of cartridge output voltages. (Modified from KAB website.) Below the chart is a link to the KAB gain calculator. It also provides a way to determine phono gain when only sensitivity is provided.

Chart of Typical Gain Values:
Cart Output..........Phono Gain
>3.0-6.0mV.........40-35dB
>1.0-3.0mV.........50-40dB
>0.3-1.0mV.........60-50dB
>0.15-0.3mV........70-60dB
0.15mV or less.....>70dB

PS: I was going to reply to your question last night but supper was on the table. You probably now have the information you need but I find this chart and web calculator to be pretty handy.
