Hey-Hey!!!,
I think Damir answered all but the capacitanceone. Go to the Fairchild Semiconductor site, and download the data sheet for the IRF820. Scroll down to the chart with che capacitance. The caacitance is greatest at low drain-source voltages and levels off after about 10V or so. Hence the 20V recomendation.

On heatsinks, anything is a bit ov a pain compared to bare TO-220's for me. But I am a bit on the lazy side. It shows everywhere: simple PP circuits, simple linestage circuits...nothing too complicated anywhere...:)
cheers,
Douglas
