shell arg parsing

I need a way to seperate an argument of a shell script,
and assign them to env variables.
Example: > foo /home2/users/tom/filelist
In this case i would want to isolate into a variable the
"home2" portion of the path argument.

On a related subject, Is there another method
to determine if a unix file path argument to a shell
script is a local file system or a nfs mounted filesystem?

Typically, i'm using sh scripts.
Thanks

Question 1:
The following line will assign the first element of the pathname given as the first argument of your sh-script to the variable 'var'.

var=`echo $1|sed 's=^/==;s=/.*$==;'`

Question 2:

# this gives you the mount point of $1
mp=`df $1|awk '{print $1}'|tail -1`
# if the mount point contains a colon, it's an NFS mount
if [ `echo $mp|grep -c ':'` -eq 1 ]; then
# NFS mounted
else
# no NFS
fi
