I use them for leds IF I need them. Your code simply needs to disable JTAG as it starts. Make sure that the reset pin is wired up to the JTAG header and then the programmer/debugger can get hold of the chip. Of course you can't debug those lines with leds and you will need to turn off the code that disables JTAG during debug.
