I read that it's inadvisable to use a polarized filters on anything but a tripod as the light reducing effect has to be compensated by an increase in shutter speed and/or aperture.

It's about the shutter speed.  If the ISO was lower than 400, and the shutter speed was higher than 1/2000th, at f/5.6 to f/8, then in your situation, a polarizer would be fine (though it's debatable if it would be needed)...

A polarizer (if needed) would be fine hand-held at 1/30th if shooting stationary objects.

But, given your goals, I don't know if I'd add a polarizer to the mix.

The main thing is, keep your ISO as low as possible, try to use f/5.6 and smaller to maximize depth of field, and try to have a very fast shutter speed.

It's a balancing act, but blurry images are no fun, so boost ISO before dropping shutter speed too low...  On the D7100, a well exposed ISO 800 shot looks great, but I'd still start at ISO100 and go from there.
