DVD reader or CD burner should go in favor of DVD burner?

Clear Day
I need some advice, please.

I have a 2800+ Athlon w/512 meg ram, 120 gig HD, DVD reader and CD burner,
and using Windows XP Home as my OS. I just bought a new Sony DRU-530A DVD
burner and want opinions on which of the disc drives I presently have would
you sacrifice? (I only have 2 bays available)
I bought it (Sony) to burn Data DVD's to b/u my files/system. I also want
to use it to copy some DVD's I OWN and to burn some of my best VHS movies to
DVD. I deal a lot w/mp3 files, some pictures and a few videos I've dl'd from
the net.
The drives I presently have a
"JLMS XJ-HD 166S" as the DVD reader and,
"LITE-ON LTR-48246S" as the CD burner.
I also use a Sony Mini-Disk player/recorder, model MZ-S1 which requires the
"Sonic-Stage" software to download mp3 files to this device. The new Sony
DRU-530A DVD burner I want to install has the Sony
format "ATRAC-3" for compressing mp3's down to the point one can put 490+
songs on a CD-R. I don't use this presently but will when I buy a new
portable cd player, it will be a Sony w/ATRAC-3.
My question is; if my best option is to keep the present CD burner I have
and replace the DVD reader w/the Sony DRU-530A DVD burner will my 2 CD
burners work in harmony or could there be a conflict?
And lastly; if I keep the DVD reader I have and delete the CD burner for the
new Sony DVD burner could I "read" DVD files directly from the DVD reader
and copy to the DVD burner? Which would be more advantageous?
Any help will be GREATLY appreciated!
Thank You.

The DVD burner will also burn CDs, so I would keep the two DVD
devices and take the CD out.

Sorry, Alex, I have to disagree. A CD burner will burn faster (my DVD burns
CDs at 24x, while my combi drive burns at 2½ times that, ie 60x). Therefore,
if the CD burner burns faster than the DVD, then I'd lose the DVD-ROM as the
DVD burner will, obviously, read DVDs as well. Of course, I have the best of
both worlds, as the combi will read DVDs.
