The easiest way to force your computer to do a filecheck is to run the 
below command as root.

shutdown now -Fr

This will reboot your computer, then force a filecheck.

Dropping into maint. mode could be caused by trying to mount a volume in 
/etc/fstab as a type that it is not. I believe setting the last two 
numbers to anything but zeroes will drop you to the shell.

Run the command mount. This will give you an output with the currently 
mounted filesystems. I unmount the filesystems that I try to check. I 
believe that you will be prompted to unmount the partition before fscking.

As for 3 and 4, no real suggestions.
