MC908QB8 board design questions

Hi all,
I'm new with the HC08 and its MON08 programming interface. Normally I work with the HC12 (BDM).
Thing is that I need to design a new board with the MC908QB8 (16 pin) and looking at the MON08 interface, it seams that 6 pins of the MCU will be used for the MON08 interface... I need to use those pins for the application so my questions are:
1) What is the best way to program/debug the MC908GB8 without loosing the MON08 6 pins of the MCU?
2) Is it possible to continuing to use all the MCU pins for application purposes instead of MON08 interface without using additional signal switching hardware?
It's a pity that the MC9S08QG8 is low voltage...
Thanks in advance for your comments,
