From analyzin the Windows Dir, The most Two Dir that contain files that can be deleted are 'Rings' and Touch Mobile Guide' over 15mb of space. Just delete the Ringers that you don't need, and the entire Touch Mobile Guide. You can back them up before you delete them.

For Opera you can change the Cache to the Internal Storage by adding the following to the Opera.ini file in the Windows/Opera9 folder uder the User Prefs section:

Cache Directory4=\Internal Storage\operacache\

You will also need to create the directory on the Internal Storage called operacache. Once this is done just delete the cache folder in the opera9 folder.
