There is a misapprehension that proper spoke tension might be in some way related to rider weight or bike use. It is not. Every rim manufacturer publishes or can give you the proper spoke tension for their rims. Rear rims' tension specs will be different from front rims because of the different spoke angles between drive side and non drive side. These spoke tensions will be the same for any use of a particular rim, no matter how many spokes it has.

You will do fine with the 32H rims. As others have pointed out, a reputable mechanic or wheelbuilder will need to check and possibly retension your wheels. Or they may be fine. I ride a tandem with a 450 pound all-up touring weight, running 36H rims and 14-15 DB spokes with never a problem. My rims are not eyeletted. I use DT Competition spokes.
