The hardest thing to find is an apple SCSI card nowadays. The other stuff
can be had cheap.
Most cost effective hard drive is to get an external SCSI-1 case. The case
has a CN50F pass thru connectors on it and there is a 50pin ribbon cable
inside to hook to the drive itself. Look for an "external scsi" on ebay.
Some ads will be for enclosures by themselves, some will have drives in
them. Nowadays the most of the external drives on ebay are many GB in size, but if you find one in the 250mb-1gb range that should be quite sufficient
for an a2. If you can't find one with a drive in it, just buy a SCSI-1 enclosure by itself then find a nice 50-pin SCSI drive to put in it. You should be able to get the pair for under $20 plus shipping.
For a CD-ROM the Apple CDSC and CD150 I have personally tested and they work fine. I think there are others listed in the comp.sys.apple2 faq that work.
I see CD150s on ebay every now and then (again-- $10-$20 should be max you
will have to pay for one of these) but not very many CDSCs). But CD Roms
for an A2 are rare. No application/game CD-ROMs per se-- most are just archive/data type CD-ROMs (file libraries in *.SHK format).
As far as writing CDRW or reading DVDs, no. But if you install the ISO9660 drivers in GSOS you should be able to read most CDROMs formatted on PCs--
but you can't do much with anything other than plain text unless you burn an ISO CD of *.shk files. You can play audio CDs too... but you have to use
the headphone port on the CD drive for audio, I don't know of any way to
route the audio through the GS speakers unless there is some stereo card out there with a line-in port?
Then you would need cables. From scsi card to hard drive you need a DB25M
to CN50M. If you have an external HD and CDROM and need to connect them in
the chain then you need a CN50M to CN50M cable. Some drives have
terminating resistors but a CN50M terminating plug to put on the end of the chain is always nice to have. Again, cheap. Just search for SCSI cable on ebay and there should be a bunch.
I recently found out that using appletalk to access the CD-ROM drive of a
mac performa over a network connection is not a noticable speed difference
over using a local CDSC with a Rev C SCSI card. The mac can read the CD
much faster which makes directory navigation a little better, but the lower bandwidth causes slowdown when you need to copy a lot of files over. I use
a mac for backing up my a2 hard drive, etc. over the network so I just keep
a data CD in the mac CDrom and whenever I need to pull something from the archive I just map the network drive and it is there.
comp.sys.apple2 faq should have directions regarding the drivers you need to install in gsos to get the devices to show up (scsi.manager et al) as well
as instructions for formatting and partitioning your HD.

How hard is it to install a SCSI card in a IIgs and then add an external
hard drive or Zip drive?
Are drivers available to add a CDROM? What about a CD-R/W?
