On both the Photoshop CS works fine. But on Mac it seems to speed up faster. The startup is much faster than on windows but relative to the velocity of the CS2, it indeed is faster. So yes, photoshop cs3 is better at functioning on an intel mac rater than cs2, due to the faster startup.

Yes.Basically, put all the PSDs you want to convert in one folder and create a new folder for the output JPGs, then create a simple action that reads a file from the PSD folder and writes a JPG to the new folder.

You can also perform other actions at the same time, like resizing, autolevels, sharpening, etc.

You can try using the "select color" instead of hue and saturation. Select the red and start subtracting all colors except black. Then select nuetrals and do the same. Then
select white etc. This will help if you want to maintain any shading in the "chair".
If you path the chair and delete it' you lose any shading
and what from the image. I hope this helps.

The option to turn tool tips on and off is found in Preferences > General.
