Bit depth, is color depth I assume. 24 bits, that is 8 bits per color channel, is what you need, but before you start to tweak the exposure and color and curves etc, it is better to have more then that, so your end result looks better. After that you can go back to 24 bits. A scanner might do 30 bits or 36 or so, but if it's more then 24 Windows will use 48 bit as the next step. So it doubles your file sizes.
Dynamic range is the range the CD can still handle. Since that is logarithmic, it's a power of ten. So a range or 3 is a factor of 1000 (10 to the power of 3). Specifically for slide film it is important to have more rather then less, because of the high contrast of the slide.
