Hi Daza ...
Welcome to LQ :}
As for your question #1:
since this can pretty much depend
on the actual hardware I'd ask you
to provide more information on your
machine and rodent, and also whether
you want to use both the touchpad and
USB mouse or use the just one at a time.
It might also be a good idea to have
a look at Linux-Laptops
has a host of information & links to
specific hardware ...
As for #2:
How do you connect to the cable? USB-
cable modem, PCMCIA device? What brand/model
is the cable modem? Does the ISP give you
a fixed IP or are you using dhcp?
