My problem is that I haven't a clue yet about shutter speed adjustments, or any
other adjustments to the camera that may be needed, when they may be needed,
or even how to make them.
So far, I'm amazed at how good my pics are looking with the built in flash
and default factory camera settings. I probably need to get over having to
spend $250 for a Canon flash!
Hehe if this is your problem, I would probably hold off on spending more money until you know what you need 
With camera gear, its not about having 'everything', unless you are filthy rich, but about having the gear you need for the photos you want to take.
Considering you bought a Point-and-shoot model, im guessing you wanted a simple but good quality camera to take quick easy shots of friends and family, maybe for a little bit of online use for facebook/personal blogging purposes. If thats the case, you might get away with whats on your camera, as you won't need expensive pro gear.
If you are looking to do photography as a hobby, and image quality and reliable results are the most important thing to you, id trade in your G9 for a 350d with the kit 18-55mm lens and go from there.
Shoot with what you have for a while, and when the shots you want to take aren't possible with the gear you have, look at what people are using to get those shots.
Cheap camera gear is bad camera gear, theres no 'hidden bargains' to be found even on eBay. In fact, in my years of experience ive found this forums Buy and Sell sections to have some of the best deals out there by quite a long shot. Its used gear, but usually used by photography buffs, who take good care of their stuff 
I hope this helps a bit! Personally id recommend saving your money until you are a little more sure about what you need. If you just 'need to buy something', get a useful bag for your camera that doesn't cost too much
