The PIC's ICSP pins are not available through the 6-pin connector. The bootloader that's on the chips is a serial bootloader that uses the PIC's USART to download code and write to the program memory. If you use the ICSP pins to download code you have to have a hardware programmer like the ICD2, but if you download the code using the bootloader all you need to have is serial port on a PC and an RS-232 to TTL converter.
