Downloading pictures always requires software of some type. If you buy a card reader, Windows XP will be able to see the memory card with its own software. Readers often come with software if you have another OS that won't do this automatically.
Even a good $500 P&S has higher image quality than 35mm film.
IMHO, one good place to start would be something in the "A: series of Canon.
