I just landed a 04 Touring at a great price. I would like to upgrade the stereo system but I would really prefer to retain the stock head unit. How can I best upgrade using stock speaker locations? Will a speaker upgrade without new amps make a difference? Somebody help a newbie....

There's a lot of work since you wanna keep your stock HU. You can upgrade the speakers, you will need an amp. Also line-out-converters (LOC). Go down to a stereo shop and listen to what they have there. A lot of people can recommend solutions but everyones ear is different. What I may like, you may not.

Look at Frankmusic's diagram at this thread. I followed it & sound is awesome while retaining the Bose 6 CD HU. I also added the Sirius digital:
