Is the JPG format most suitable for print and web advertising?
The BEST file to give a print shop is a vector file. If you have something important like a logo, you should have it in an Adobe Illustrator or EPS file so that it will stay sharp and accurate no matter the size (unless it is photographic, then PNG or TIF). That will be what your print guy wants. From that file you can make almost any other file you want. JPG is the most used (I believe) file format for the web. That is what I use. It is a lossy format however. That means every time you copy the file it loses some data.
No, plain and simple.
It’s a "lossy" format and unless you save it at 100% quality artifacts can form and mar the image.
Generally I’d suggest PNG’s as they support transparency and aren’t lossy. Plus they’re a relatively small file.
When working on an edited image you would probably want to keep it as a PSD or XCF or something that supports layers. they’re big but its much easier to work with, and prevents you from ruining images if you’re smart with it.

I’m partial to PNG myself.

The JPG format should only be used for images you want to display at screen resolution (72 dpi) on web pages. JPG’s do not print well since the compression creates many distortions.
