for a 140MB disk I would compine /root and /usr so that they share 
tmp space.   How  much you need depends upon what you plan to load.
For a full workstation developer package (excluding the LPI junk),
you need around 60MB.  add an extra 10MB for tmp space and kernel
reconfigurations.

Nope.  Well, you don't have to re-initialize the disk, but you do have to
reload.  Might as well reload.

0. go to single user mode
1. Shrink /usr2 (see the FAQ posting for related info on setting up partitons)
2. mkfs it
3. mount it.  
4. create lost+found
5. mount /usr
6. cd /usr; ulimit 99999999; find . -print | cpio -oBcv | compress > /usr2/save
7. cd /
8. umount /usr
9. adjust the size of /usr, mkfs, make lost+found, mount it
10. cd /usr; uncompress < /usr2/save | cpio -idvmucB

You can remove the dos partition, but you cannot change the size of the unix
partition

See above.
