Default Dithering

Hey what's up everyone? I have a few quick questions about dithering.. if there's already been a discussion on this lately, please route my signal to the appropriate bus and I'll check out that post for some answers too.
Anyways here we go:
1) If I have a dither plug on the master when before I bounce, do I need to have "use Audiosuite dither" checkmarked in Prefrences>Processing? And do I need to switch this each time before bouncing, depending on whether I'm re-importing it into a 24bit session or cutting to CD (16bit)?
2) When would I use 18- or 20-bit dithering?
3) If if have an L1 Ultramaximizer plug on the master set to 16bit Quantize, do I need either the Audiosuite Dither on (in Prefs) OR a Dither plugin on the master fader?
4) Do I really need ANY dither from these 3 sources (plug, prefs, L1) if I'm bouncing to a 24bit file (to re-import)???

Thanks for any help on this subject - I really should know this by now, but I've had tons of other stuff to get down first. Later.

A really quick answer (you can search online for the long, detailed answers - try www.digido.com):

If you're bouncing a 24 bit file to keep working in 24 bit, don't use a dither plug. You only want to dither on your final master. Mastering engineers prefer getting 24 bit files so they can do the final dithering. 18 and 20 bit are rarely used in any current formats. Some ADATs run 20 bit. Only use one instance of dither, preferably POW-r or IDR.

If you're dithering the output of the master fader somehow, why would you want to dither the fade files? Wouldn't they get "double dithered" that way?

Where (or should I ask when) does the Digi "Dithered Mixer" actually dither? Under what conditions? Is it going from 48bit down to 24bit? Or is there more going on?
