fsck is a file system consistency check program, analogous to the scandisk
program in windows. Whenever you shutdown your machine improperly(for
e.g. without unmounting the mounted filesystems) there is bound to be some
kind of inconsitency in the filesystem and fsck attempts to resolve this.

Right. it is a good thing to fix those errors. File information such as
owner, group, access time, modified time, disk blocks etc. is stored in an
inode in most Unix operating systems. You can refer to any good book on
Unix fundamentals to understand what inodes are and why they exist.

I am not sure why your windowmanager settings got changed - hard to
believe that it could be because of the crash. Which distribution and
version are you using? The latest distros(Red Hat, Suse, Debian etc. )
all give you the option of formatting partitions with a journaling
filesystem such as ext3 or reiserfs. Journaling filesystems maintain
transaction logs of all changes being done to a filesystem and are
better at recovering from crashes than non-journaling filesystems like
ext2. With a proper plan in mind, you can also migrate your existing
filesystem to a ext3 or reiserfs.
