You can program the chip using the MicroCode Loader bootloader. But it requires that the bootloader firmware is first programmed into the chip using a normal programmer like the U2, PICKit3, ICD3 or whatever. Once you got the correct bootloader firmware in the chip your "normal" program can be downloaded over the serial port using, for example, the FTDI cable. The bootloader and the soft ICD in Microcode Studio uses the same hardware connections.

There's no way to simulate the code within Microcode studio. You need third party software for that. Lab Center Proteus seems popular.
