The bad news is a power spike could have damaged any part of your system. However - CSEL is known to be rather unreliable, I would jumper the two drives as master and slave and retry installing on your new drive. You may, however, have corruption on your old drive (especially as you cannot boot from it) which would explain your inability to copy some files, and Ghost failure. Doesn't explain your Office problem unless this is tied to using CSEL. Could try reinstalling with the new drive only in the system jumpered as master.
Sorry can not be more helpful/hopeful - best of luck
