Hi Larry,
One quick question before I proceed.  Are you doing a real "upgrade" or 
an "install"
An "upgrade" is where SL 5.4 stays there and you just update the 
packages in it.  If that is the case, using the installer isn't the 
recommended way of updating it.  It is much easier to to an upgrade via yum.

An "install" is where you wipe and reformat everything except maybe your 
home and data partitions.

I am going to assume that you are doing a "install" or SL 5.5 over a 
previously installed SL 5.4.

If you are doing this, then you *need* to reformat the partitions that 
do not contain your home area or data.  Otherwise the install starts 
adding to what is already there, and as you saw, it can fill up.

Patitions you should format if you are doing an install.

/
/usr
/var
/boot

As Steve said in a previous email, if you can fit everything onto / 
there is often no reason to create a /usr.  Take that space and add it to /

Hopefully this is enough information, along with Steve's,  to get you going
