Wikipedia has a great section on PNG and compares it to JPG compression and GIF applications. Reccomendations on best PNG compression software as well.
Regarding PNG-24 vs PNG-8, if possible please try finding a way to save the PNG images as PNG-8 to speed up downloads. Some of these screencaptures are big (dimensionally) images and it can add up…(file-size kb)
PNG-8 is great for 256 color graphics - Use this please if you can for the screencapture edits.
PNG-24 - only for delicate transparencies and small files with 'shading' effects, which is frankly almost never.
