For the serial-to-usb you will use the DFU method, just follow this picture and your MEGA8U2 will be into DFU mode, then in short:
- Download the UNO firmware.
- Do the stuff on the picture
- sudo dfu-programmer at90usb82 erase
- sudo dfu-programmer at90usb82 flash Arduino-usbserial-uno.hex
- sudo dfu-programmer at90usb82 reset
(You can read all the steps here)

Now for the bottloader update, if you have two arduinos laying around just use this optifix sketch by westfw.

May the force be with you.
