I found out that with program memory, im only at 25%(yay!), and i got my data memory down to 000fab or something like that.
According to the data sheet for the PIC 18FXX20 family (available from www.microchip.com, look for PIC18F8520), the data space is 0x800 bytes.

This can also be seen in the 18f8f20user.lkr file, which contains the memory map. Although 0x754...0x7ff is allocated to something called "dbgspr" whatever that is and is listed as "PROTECTED."
