Yes it has been removed. If you issue the removal command again you will see an error stating that Tomcat is not installed.

ureadahead is a mechanism whereby anything that is required to be loaded at boot time is marked as such and the location is noted. This speeds up boot time because the filesystem doesn't have to go searching for the files before loading them. As you can imagine, when you install or remove modules some of them may have to be added or removed from ureadahead to keep it up to date. It's normal mechanism in modern Linux operating systems like Ubuntu.
