Wow, he wants help shooting jpegs and there are like 10 people talking about RAW.
banquetbear gave the only really useful tidbit of info. Yes, your white balance is critical for jpeg shooting. That is essential. For generic shooting, I personally use a custom Picture Style based off the Neutral style. Go to User Def picture style and select Neutral as your base. From there, I set my sharpness to 5, Contrast to +2, Saturation to +2, and leave color tone alone. This does a good job of giving nice colours that aren't oversaturated, with enough contrast for a final grade, deliverable image.
If you want to get serious into jpeg shooting, then go for it. Jpeg shooting is VERY powerful, and 99.999% of people who spout off saying RAW is the only way to go has never actually tried the FULL POWER of jpeg shooting.
One of the keys to great jpeg shooting is to get the canon Picture Style editor.

This is a very powerful program which lets you define and upload your own picture styles (via the EOS utility) to your camera. It gives you a degree of control far beyond what the in-camera menus let you. You can create all kinds of custom picture styles to stylize your photos in-camera. I mean, you can create cross process styles, or even give photos a faded vintage kind of look, or anything else. It's like loading your Lightroom Presets right into your camera. You can modify specific color channels to achieve all kinds of effects. Combine that with the power of K and SHIFT white balance, you can achieve just about any look you want, all in-camera. It's very powerful. There is a reason why Canon puts a dedicated Picture Style selector button on their cameras.
Don't be fooled. Jpeg shooting is just as valid of a method as RAW shooting. If this is the direction you want to go, then go for it!
I'm constantly practicing to be a jpeg-only shooter, so I can finally ditch these damn RAW files for good.
