Yes.

You can also remove your main drive. Install new drive there. Copy files over
with a livecd. Move new drive to old drive. Put back system drive, reboot.

Your motherboard probably has 2 IDE channels, you can connect 4 drives. So you
can potentially have 3 HDs, 1 DVD.  If you have SATA connectors you can have
more SATA drives. If you have an extra IDE-RAID controller you can potentially
have another 4 IDE drives.

I think that's for outgoing bandwidth. So connections going out of campus, no?
Then again, 2gigs a day out of campus sounds like a lot.

Fast ethernet is 100Mbps (bits, not bytes). You don't need a crossover cable,
just a hub/switch. If you don't have one, then yes,  a crossover from one
computer to the other will work.  Do not use wireless, it'll take forever;
borrow a hub/switch or crossover cable.

You can also use a usb/firewire hard drive if you have one. It better be usb2
cause keep in mind you're doing double the copy work.

My recommendation, just use the normal network, copy things overnight.

No idea.
