I wonder if you have a badly burned disk, or your cd driver is failing.

As for partitions i tend to do simply:
/dev/sda1 and sdb1 20GB (for /root raid)
/dev/sda2 and sdb2 the rest (for LVM's raid)

Then I assign the two raid1's and make then assign the large raid as
physical volume for LVM, then slice up the LVM stuff, and then assign
the first raid for root fs.  Ext3 everywhere of course.

If you want /usr seperate, then reduce the size of the root partition a
lot and make a /usr area in the LVM instead.  Similarly for /var.  The
root filesystem could probably be 1GB if you make /usr and /var use
seperate volumes instead of being part of /.
