Hmm.. I can advice you a good place to seek for anime walls and themes, but they don't have any anime tones, which's bad.
Anyways, I like this site, and I've added some walls too.. I'll make some themes, cuz they don't have yet for SonyEricsson m600i..
*sigh*
A good site still..

You also should've USB-cable to make it easier, cuz it's easier to dl straight to the PC and transfer, than use your phone..
I use myself mp3s which I have edited(read:shortened) to save space and prevent listening intros.. And if your phone supports, I can tell you it's funny. At the moment I have the theme o' DearS, and you can believe me, it's quite a surprise for people, when "Love Slave" gets on...
I can do some investigation for miditones too, but I cannot promise..
And Alucard24, you should check that out, cuz they have pretty an amount of themes...
