Jim,
The software to program the PIC or the program itself?
Microchip has made available for free the development software that you write your assembly program in - it's great, you can do all the good debug/simulation stuff in it. It compiles to a common format hex file.
The programming software (you can use Microchip's, but it works almost exclusively with their programming hardware) takes the hex file and writes it to the chip's EEPROM (or EPROM).
The development software is free and programmers and programmer software can be had for cheap or free.
PICs are great, because they give you computer control in a circuit with just one chip...that doesn't require anything but a 5V source (some run on less).
So many applications.

d,
Start with the Microchip PIC16F84. It has EEPROM (flash memory) so you
don't need a UV lamp to erase it.
I'm trying to envision writing the software for this chip. I assume you need
some kind of development tool where the program is stored until it is running as
intended, this would have to include an interface with the chip so the program
can be dumped to it. As I said I have never used a PIC device. I couldn't
imagine anything that I might do with it that I couldn't write assembly for it.
