To backup you current HD, format a external harddrive to FAT32, plug it in and away you go.
I have a 500gb HDD on my PS3, I know that it supports up to 1TB but I believe only certain models (not sure about the last).
But really 500gb should be more than enough, you can always link you PS3 to your PC via a media server afterall.
