Most likely some process is holding the file open and/or immediately recreating it when you delete it. Try the following command:
sudo lsof google-chrome/default/User\ StyleSheets/Custom.css
This should tell you what program is locking the file. You may then kill it, and (hopefully) delete the file. Failing that, a reboot should fix it good.
Should I install skype to my /home/me/ directory (or a subdirectory of
that)
You shouldn't install Skype manually. Just download and install the ".deb" package.
Should it be installed in system apps location (where is that? /bin?
/usr/bin?)
The apps are stored normally in /usr/bin or /usr/lib

/usr/bin
This directory contains the vast majority of binaries on your system.
Executables in this directory vary widely. For instance vi, gcc,
gnome-session and mozilla and are all found here.
/usr/lib
This directory contains program libraries. Libraries are collections of frequently used program routines.
So apache is installed... (in some location). Do each users public
html folder go in their /home/username/public directory? or a created
/home/username/public_html directory? or does it go where apache is
installed
It should go where apache is installed (normally the www directory). However, you can follow this guide if you want to achieve something else:
http://httpd.apache.org/docs/2.4/howto/public_html.html

/usr/local
The original idea behind '/usr/local' was to have a separate ('local') '/usr' directory on every machine besides '/usr', which
might be just mounted read-only from somewhere else. It copies the
structure of '/usr'. These days, '/usr/local' is widely regarded as a
good place in which to keep self-compiled or third-party programs.
The /usr/local hierarchy is for use by the system administrator when
installing software locally. It needs to be safe from being
overwritten when the system software is updated. It may be used for
programs and data that are shareable amongst a group of hosts, but
not found in /usr. Locally installed software must be placed within
/usr/local rather than /usr unless it is being installed to replace
or upgrade software in /usr.
Unrelated.. where should I put downloaded media (music, movies, etc)?
Can other users access these by default?
It's normally in /home/$username/Downloads
. Other users can't access these files.
Further information: http://www.tldp.org/LDP/Linux-Filesystem-Hierarchy/html/home.html
/home is a fairly standard concept, but it is clearly a
site-specific filesystem.
Different people prefer to place user accounts in a variety of places. This section describes only a suggested placement for user
home directories; nevertheless we recommend that all FHS-compliant
distributions use this as the default location for home directories.
On small systems, each user's directory is typically one of the many
subdirectories of /home such as /home/smith, /home/torvalds,
/home/operator, etc. On large systems (especially when the /home
directories are shared amongst many hosts using NFS) it is useful
to subdivide user home directories. Subdivision may be accomplished by
using subdirectories such as /home/staff, /home/guests,
/home/students, etc.
The setup will differ from host to host. Therefore, no program should rely on this location.
If you want to find out a user's home directory, you should use the
getpwent(3) library function rather than relying on /etc/passwd
because user information may be stored remotely using systems such
as NIS.
User specific configuration files for applications are stored in the
user's home directory in a file that starts with the '.' character
(a "dot file"). If an application needs to create more than one dot
file then they should be placed in a subdirectory with a name starting
with a '.' character, (a "dot directory"). In this case the
configuration files should not start with the '.' character.
It is recommended that apart from autosave and lock files programs
should refrain from creating non dot files or directories in a home
directory without user intervention.
From tldp
If I install a program through software center or apt-get, where do
they go automatically? Does the package determine this
Yes it does. As already mentioned it should be in /usr/bin or /usr/lib. However, if you are installing applications manually it's often best practice to use /opt
.

Is there some document available I can read that talks about where
ubuntu (or linux in general, i guess) puts stuff? My google attemps
lead to explanations of ubuntu filesystem instead of where things go
inside of the filesystem. A link would be appreciated.
