How to blur background of a picture and adjust shutter speed on Nikon Coolpix P90?

Hello! I've had the Nikon Coolpix P90 for quite sometime, I love the camera, I just have a few questions.
First, I researched how to take a picture that has a clear subject and a blurred background. But, I can't seem to figure it out on my camera.

This is an example:

I can't seem to figure out how to focus on the subject and blur the background. I tried everything that the sites have told me, but it still doesn't work for me.

Second, I would love to try to do light graffiti.

Example:

For that, you have to adjust shutter speed. I'm having a bit of trouble trying to figure out how to adjust my shutter speed.

I'm very much into photography, therefore I would love to find out how to do both of these things on my camera.So, if you have any ideas on how to do them, please let me know! Thank you so much!
