/sbin is only in root's path by default - any user can run a binary in 
/sbin (assuming fs permissions allow them), but they'll often fail as in :

"/sbin/fdisk -l /dev/hda" as a non-root user will fail as the user can't 
open /dev/hda.

/sbin is supposed to be always on the root disk (/) (i.e. not 
partitioned seperately), therefore if you happen to screw up a 
filesystem you _should_ be able to boot the box and fix it (as /sbin is 
still there). (Some people have /usr as a seperate partition, for 
space/performance considerations)

/proc is the mount point of a virtaul file system (procfs), which shows 
you some innards of the Linux kernel - e.g. /proc/kcore is a _very_ 
large file, and should be as large as you have RAM used; 
/proc/bus/usb/devices should list all usb devices attached, 
/proc/scsi/scsi does the same for scsi stuff etc.
