It's probably worth shooting at a higher resolution, as well. Shooting at a lower resolution (1600x1200) is throwing away picture information. Even if you resample it to a smaller image later, at least the details is there - which can help with the resampling, and it also gives you more room to crop out extra detail.
A higher F-stsop (as used here) is a good idea as it gives you a greater depth of field, so more of the will be picture will be in focus. Still, for portraits, a very shallow DoF is often desired (with the eyes in razor focus and the rest of the face a little soft), but with a point and shoot, you're pushing your luck to hope for it to focus exactly where you want like that.
You also want a low ISO to minimize image noise, and a tripod is definitely of prime important if you're going to be shooting in lower light. Equally important to the tripod is for your subject to remain absolutely still.
For photo editing, it depends. The free Irfanview can do about 95% of what most people need Photoshop to do. It crops and resamples faster and easier than Photoshop and has a bunch of built-in filters (including unsharp mask and red-eye reduction) and can even use Photoshop filters. You can also do basic image manipulations, like change color levels, add text, etc.
It's not Photoshop and does not pretend to be, but you'd be amazed at just how much you can do without waiting for Photoshop's long startup time. Obviously if you want do things like edit out the crane behind Cinderalla Castle, you'll need a full-fledged photo editor.
Master Mason - I was just re-reading the thread to see if I missed anything and you're right, I did weigh in on it. Am I that predictable?

Hey, I LOVE that program. I couldn't live without it. (Well, I could, but any photo tasks would be far more painful!) I highly, highly, highly recommend it. And I have absolutely nothing to do with the product itself so everyone is welcome to enjoy it guilt-free even if they don't like me!
