is it possible to use the mmc and spi without removing the mmc card?

    Yes. There is a chip select pin on the MMC card that should only be enabled when the MMC card is being accessed. The chip enable line is shared with the button on the camera, so be careful for any strange interactions there. When the MMC card is disabled, you can enable whatever else is using the SPI bus and talk directly to that device.
