The out of focus in the background in the above photo is referred as bokeh correct?
It's a good question that only someone interested in understanding photography would ask.
There are a couple of fundamentals you must understand to take good pictures:
Cameras don't take good pictures, photographers do.
Take lots of pictures, but take notes. If you take 20 pictures of one thing while experimenting with camera settings, but don't remember what you did when, all those pics aren't helping. Yes, the meta data will record a lot of it for you, but only you can put down lighting conditions and why you chose those settings.
About equipment- Take a look at these two pics:
Which was taken with a $2K DSLR and which was taken with a cell phone?
About lighting...
One was taken indoors with controlled artificial lighting and one was taken outdoors in bright sun/shade. Do you know which is which? It's about using the light you have more than forcing the light to your will (which also works if you know how).
Spend some time on this website:
How to Take Better Pictures Ken Rockwell offers up some great advice on that site.
Just for the record, taking pictures of anything with a shiny, reflective surface is very difficult.
