I'm not sure that I understand the problem.  You have the tar file and you 
just want to dump the contents into the default (current) directory?  Or 
you want to be able to send the tar file to someone else and have it dump 
into their default directory?  For the former, unless a directory named 
wordpress already exists, I do this:

tar -xvzf wordpress.tar.gz ; mv wordpress/* . ; rmdir wordpress

But if a filename might begin with '.', this will be needed:

tar -xvzf wordpress.tar.gz ; mv wordpress/{,.[^.]}* . ; rmdir wordpress

What's so wrong about that?  ;-)

For the latter, you need to recreate the tar file by going into the 
wordpress directory and creating the tar file from there.

cd wordpress
tar czf ../wordpress.tar.gz ./{,.[^.]}*

Right?
