I really don't know why people work out what the config should be. Microchip supply a template file that you should use. You'll find it in C:\Program Files\Microchip\MPASM Suite\Template\Code\f88temp.asm
In the template file you will find this config line,
__CONFIG _CONFIG1, _CP_OFF & _CCP1_RB0 & _DEBUG_OFF & _WRT_PROTECT_OFF & _CPD_OFF & _LVP_OFF & _BODEN_OFF & _MCLR_OFF & _PWRTE_ON & _WDT_OFF & _INTRC_IO
It's self explanatory. If you want LVP then change LVP_OFF to LVP_ON.
As it happens, it's already setup for internal oscillator with the pins as IO.
If you want a different osc setting then change INTRC_OSC to one of the following, _EXTRC_CLKOUT, _EXTRC_IO, _INTRC_CLKOUT, _EXTCLK, _HS_OSC, _XT_OSC, _LP_OSC
If you want a complete list of config values then look in the P16F88.inc file located at C:\Program Files\Microchip\MPASM Suite
