I want to programa 18f2550 with nothing more complicated than a usb
cable..........

Now I know that first time round I need to serial program into it and then....
(a) bootloader into pic

(b) assemble all my code starting above the bootloader (say org0x800 etc)

(c) have some software to ''send'' this assembled hex file to the pic
I have no idea what to use for (a) as they are a few out there and for
(c) I have seen nothing but people must be using something!

Try Oshonsoft Pic18_Sim_Ide at www.oshonsoft.com. The simulator,
basic compiler is 29 euro. There is an addon for USB. Under projects
you will find a bootloader for the 18F series. The bootloader uses
the serial port which may be better than using the USB for
bootloading. You can play with Pic18_Sim_Ide with out paying for the
product to get a feeling for it. 29Euro is a great deal.

Well to put the bootloaderin you could use a galvawisp,
http://www.picbasic.nl/galvawisp2_uk.htm. I got one and like it a lot,
cheap and reliable.

For the c part is google your friend:
