I guess it depends on your definition of "really need". Having them is a plus Use them when needed.
The lens hood and adapter help shade the lens from glare and "reflections". Most of the time they can be eliminated by not letting the sun shine into the lens.
Press the Disply button on the camera and your LCD screen will change (I think there are 5 different display settings). Keep pressing and you will see the horizontal (and verticle) grid.
I use the UV filter to protect the lens and I leave it on all the time.
It's a lot easier to clean the UV filter.
Hope that helps

Where is the horizontal indicator on the camera? I was reading Joe's page.
