When saving for web you would never want to change the resolution to 300. A high quality JPG image using save for web will almost always be less than 100k in size. You should have the color mode set to sRGB and usually that is the best default color space for the camera (as well) if you do mostly web output. Elements 3 is an antique and really needs to be upgraded. Naturally, if you shoot RAW you can change your color space at anytime in the RAW converter (if for example you later need Adobe RGB, etc). Also keep in mind that any image with a height larger than 600 pixels will not be fully viewable without scrolling on the "average" browser (1024 x 768). G1 will resize the "large" preview image to 600 pixels high for portrait mode.
Here is a typical look at the Save for Web Interface:
This example would produce a file size of 50 to 60 K on average.
