Sorry for the delayed response.
I'm not sure if it's just my computer, but if I view an Arduino page (non forum pages) then try log into the forum, I cannot. It just loads to a white screen. Only when I log in directly before looking at any other (non forum pages) it works properly. I have to restart my computer to solve this.
I think I may be confusing myself with the 2560 solution.
I'll refer to http://arduino.cc/en/Tutorial/ArduinoToBreadboard
to burn the bootloader using my Arduino Uno board, and also to upload my programs.
To confirm, by using this method, TXO and RXO from the 2560 can be connected in the same way as shown in the above link with no problem?
