The Disk Usage Analyzer is available under Ubuntu > Accessories > Disk Usage Analyzer. It provides you with a snazzy pie graph showing what files and folders take up the most space:
The documentation on it is a little sparse, but you can find more information on the Ubuntu wiki, and the project page.
If you're interested in using the command line, there's du which is described here.
The complete answer is to check out the Filesystem Hierachy Standard documentation on what stuff goes where.
But in your case, if you want to know where a particular executable is (for example firefox) use
which firefox
And you will get the full path like this
/usr/bin/firefox

The journal is stored in a separate space of the partition, you cannot access it directly. You can use
sudo debugfs /dev/sda#where the#symbol is the number of your partition, and then usinglogdumpindebugfsto print it out. The output is confusing though.Generally, as a regular user, you don't need to know about the journal. Using
ext3/4will be sufficient to prevent data loss (in most cases).This link might help: http://www.linuxforums.org/forum/red-hat-fedora-linux/121074-ext3-journal.html
