RE: chain reduction
Decide on your chain link length. Decide what gear ratio you want (R). Choose appropriate number of teeth for small diameter chainwheel (at least 11). The large one will have R times as many teeth . work out their diameters (=no. of teeth*link length/pi). The distance between the wheels has no effect on the ratio, but if they are too close then you won't get enough wrap on the small cog.
