If approximate frequency is sufficient (no consideration of doppler) then a sheet of graph paper with three frequency scaled drawn on it worked for me in the pre computer days.

Also if say I am planning on a downlink of 145.950 will Paul be looking at the same frequency?

No. You will both have different doppler shifts so, for a common uplink frequency, your downlink frequencies will differ.
