I think the question of resizing images is more a question of quality and speed. There is code for J2ME to resize images, just ask google :-). But the results will not be very nice, because, on many devices you have other screen-dimensiosn (240x240, 240x320 e.g.).
If you only target new devices, than this should not be a problem. Just include some more Graphics or build Midlets for specific devices.
