    It is for write only. You can read as much as you want. Data retention is on the order of 40 years. After this, you may run into trouble!

    Check the datasheet for the specific PIC. For instance, the PIC16F88 datasheet says, "1,000,000 typical erase/write cycles EEPROM data memory typical" while the PIC16F84 datasheet says, "10,000,000 erase/write cycles EEPROM data memory". As Ron already noted, reads are unlimited.
