Questions on ArchLinux for the blind

[Cleverson Casarin Uliana]

Hello all:

I plan to give ArchLinux a try, using Chris Brannon's talking Arch CD. I 
have 3 questions before trying it:

1. After installing and configuring the base system, is it possible to 
set up the x server plus Gnome and setting up Orca without sighted 
assistance? There are instructions in the beginners guide to install a 
graphical environment, but no instructions for setting up Orca. Could 
you write down such steps, in case it is accessible to do?

2. Is there any problem configuring another keyboard and locale during 
the installation? My native language is Brazilian Portuguese, so I will 
have to set my localization options and change the ESpeak voice after 
rebooting into the installed system, right? In the future, perhaps  I 
could even try remastering a localized Talking Arch for me.

3. My machine has a Pentium D dual core processor, with 1 GB RAM. Is it 
worth installing the 64 bits version, since I don't have much memory?

That's it for now. Thanks,
Cleverson
