My PIC design is going to use a 10MHz TTL clock for the processor but my
plans
are to use a watch/TF crystal 32.xxxx KHz for the TMR0 clock input, and
thus
produce a 1 second interupt (so I can have a counter(s) running on a 1 sec
decrement).

Why do you need to do this with a separate crystal?  You can easily divide
the instruction clock to 1 second in software.  You can set up periodic
interrupts using timer 0 and possibly the prescaler, then divide those
interrupts further in software so that there is a section of the interrupt
routine that only gets run once every second.  This is even easier if you
have timer 2 available with its programmable period.
