So here's the thing...I'm seriously gravitating towards shooting sports. With the youth soccer, little league, and high school sports events, I figure I can stay busy.
Something to be aware of... event photography, which is what this is, in poorly illuminated gymnasiums can be very trying for even the best equipment. So be prepared for that fact that you are necessarily making some large compromises! There will be fewer problems with the outdoor sports though.

I currently own a D5000 which was my first purchase. I got it used from Adorama at a great price ($169).
Question 1: I've read that more megapixels does not necessarily mean better images. Will the D3300 give me improved image quality over the D5000?
Question 2: Will the D3300 let me shoot 5 fps in RAW?
The D3300 can shoot at a maximum frame rate of 5 fps, while your D5000 is limited to 4 fps. You won't see a difference.
The D5000 has 12.9 MP and the D3300 has 24.2 MP. If you post images to the web, or otherwise view them on a computer monitor, there just will not be any difference. If you want to print them at 16x20 the differences will start to show up, and at 24x30 will be significant. That applies to full sized images... and if you like to crop them the difference is greater the more you crop!
Here is a set of graphs that you will find interesting:

The bottom line is that the higher up vertically the graph is at any given horzontal location (ISO), the better the camera is. That line way down below everything else is a D2X. The brown line is the D5000, and green line is the D3300. The top line is a D5200 (which is almost identical to the graph for a D7100).
Each of the newer cameras is at least somewhat better than the older D5000. Not by any huge margin though. If you have to shoot at an ISO above 200 but below about 2000, they are pretty close. At ISO 200 the D5200 is significantly better. As the ISO is raised above 2000 the D5000 loses ground (with more visible noise).
At ISO 6400 you have to absolutely nail the exposure just to get a useful image, and noise cannot be avoided. Even a small difference between those lines will result in better images for the camera that has higher dynamic range.
Just to give you some perspective, click on the D4S. The difference is what $6000 will buy.
