Help in upgrading a Apple IIgs

[pliethen@globaldialog.com (Peter Liethen)]

Hello all,
 I recently got a Apple IIgs from a friend who was going to throw it out.
I want to try and make it a useful system for my brother to use.

It is a ROM 01 IIgs, with 1.25 megs or RAM (Expanded with a Applied
Engineering GS RAM III) I want to expand the IIgs to atleast 2.25 megs,
4.25 would be the best. It also has a Datalink 2400bps modem in slot 2.
Now, on with the questions.

#1. Where can I buy RAM new for my setup? What is the cost? It coudn't be
more that $9 a meg.

#2. I have a AppleTalk network. Can I integrate the IIgs into the network
and access files of a Macintosh hard drive?

#3. What would I need to add a standard external SCSI hard drive?

#4. Can the IIgs be sped up without overheating the system, and without
replacing RAM and other things?

#5. Can I use a ADB-powerd modem on the IIgs?

Sorry about all the questions, I don't know must about the IIgs. Please
e-mail me with a response, as I can't check newsgroups as much as I would
like to.
