If you use FSR you don't have to set any bits for between bank0 and
bank1 (it is explained in the data sheet).
So, to copy a register from 0x021 in bank0 to 0x0A1 in bank1:
MOVLW   0X021   ;value of register to copy
MOVWF   FSR     ;point to that register
MOVF    INCF,W  ;move and
MOVWF   TEMP1   ;save contents in a temporary register
MOVLW   0X0A1   ;value of register to save in
MOVWF   FSR     ;point to that register
MOVF    TEMP1,W ;move contents and
MOVWF   INDF    ;save it in that register

Loop that for all your other registers.
Read the data sheets on using the FSR, it is a very handy function to
use.
