Basically, I try not to use the JTAG pins for anything else if I can help it. Very wasteful! Remember that JTAG needs to be disabled if you want to use those pins, either via the fuse (permanent) or by writing to the JTAG disable register in your code. I would only use the pins for something like reading a dip switch (with series resistors) or indication leds which could be simulated during debug.
