REAL ICE with PIC 16F648A

Hello

I developped a circuit around the PIC16F648A. Using MPLAB X-IDE without 
any ICE for debugging is hard for me, so now I think I'm going to buy a 
ICE like the REAL ICE, which also can be used in the near future and is 
a top product.
For the 16F648A I have to use the Header Board AC162053 as stated here: 
http://www.microchip.com/wwwproducts/DevTool/PIC16F648A.

Now my question:
In my circuit, all I/O ports of this microcontroller are connected (even 
on RA5 there's an external reset circuit with resistor and capacitor)
Am I right that using the Header Port has a lot of advantages, in such 
that I do not have to change anything om the port connections to make 
the REAL ICE working properly?

Newer PIC devices which do connect directly by a RJ-11 to the REAL ICE 
must complain with several requirements regarding MCLR, PGM, PGC and PGD 
connections.

So all I have to do is pull out the microcontroller from the circuit, 
put in the Header Board and debugging can start thru MPLAB X-IDE?
Of course In-Circuit Programming is not possible that way, but that's no 
problem.

Thanks
