I would be prepping my stock by hand, and my sharpening kit is currently a set of 3 diamond stones (300 grit > 1200 grit) which has served me well thus far.
You may want to invest in more sharpening equipment. Most of the time when my blades need attention my starting point is a 1000 grit stone. This will take care of small nicks and dulled edges. In your case a higher grit stone and a stropping set up may be all that is needed.
Of course it seems there are as many different ways to sharpness as there are people trying to obtain a sharp edge.
My shop is unheated. In the winter my sharpening is done on oilstones. In the warmer months my sharpening is done with water stones. They can both produce a sharp edge, they are just a bit different in the process.
