Overclocking it 25% might be asking a lot, but assuming it's running at 80MHz those serial settings look to be correct.

You might have better luck powering up @ 20MHZ and then enabling the PLL by setting OSCTUNE = $40 once things are up and running.
I'd start with
Code:
config FOSC = HS2         ; HS oscillator (High power, 16 MHz - 25 MHz)
config PLLCFG = OFF       ; Disabled
config FCMEN = OFF        ; Disabled
config IESO = OFF         ; Disabled
config PWRTEN = ON        ; Enabled
