MrSak I would highly recommend you learn to use PhotoShop. The latest version is PhotoShop CS but, I use 7.0 and it's just as good. By use of multiple layers and filtering you can make your scannings pixel perfect.
Below is an image I drew pencil and paper and scanned into computer, then adjusted. The easiest way to convert a scan to a good image is by simply adjusting the brightness and contrast. This will bring out your lines and remove the paper look.
To use the trace method that Pertb. recommended I would use a line tool to trace over and make as many lines as you need to get the same depth, this will be easier than tracing over with the simple paintbrush tool which is a bit harder using a mouse and often makes for unsteady lines.
At least, use an optical mouse.
And, if you're super get a Wacom tablet or something similar.
