Save all data on SDcard???

[RmiXDflavoR]

Hey was just wondering if any of you have like some tips or ideas on how to place all the program memory on the SDcard.I do install all my programs,music,fotos,ect. on the card,but some of these programs create folders on the actual phone, is theyre a way to make the default to the SDcard? Also can I copy the Themes folder off from the phone over to the SDcard or will they not work well?? Sorry for the long post and thanks for any replies.
