Sounds like what I did when installing gentoo.  I booted from a set of 
slackware floppies, partitioned the hard drive, formatted the filesystems 
and a little swap, installed the base system, and chrooted my installed 
system.  I installed linux and was running it without ever rebooting!

For partitions, I made a small one for /boot.  I found that this had to be 
done for older computers with large hard drives.  There was no way to get 
this old Compaq to boot a kernel from a 160GB hard drive.  The hardware 
was too much for the BIOS to chew on.  It needed the small bite sized baby 
food portions below the 512MB limit.

The rest of the partitions can be divided up in any way imaginable or left 
alone in one big chunk.  I usually have a small swap partition after that.

I wouldn't worry about making a seperate partition for backup files, but 
it doesn't hurt.  Even though I never destroyed my own stuff, I usually 
use cdroms for backups.  Backing up on a seperate, or removable drive, is 
a good method of backups.  Unless the drive gets dropped or bumped against 
a surface...

Most distributions will give you flexibility.  Beware of the "easy" 
install options that will do everything for you.  That's the "format 
everything and get it working without any user input" option.

Does that answer your question?
