Piano notes are easy to learn, both on the staff and on the keyboard. The following images should be helpful for familiarization with the piano keys and how they correspond to the music.
First you'll see the basic 38 notes every pianist should know by sight on the grand staff (19 notes in bass clef, 19 notes in treble clef).
Then, you'll see a more extensive listing of the bass clef notes and the treble clef notes separately. Hopefully this will go far to aid your understanding of how the notes on the keyboard relate to the notes on the music staff.
Knowing the notes on the staff, and where to find them on the piano, is definitely an important part of learning to read music at the piano. Take the time to learn each note and be able to find it quickly on the keys. It's worth it.
[As you become more and more familiar with the notes on the staff and on the keyboard, you will find your understanding of scales and chords growing more and more clear. Not only will your reading ability improve, but your ability to learn and memorize music, analyze music, and write your own compositions. With basic note reading and keyboard geography skills, all of these things become part of your piano-playing existence. Without the basic note knowledge, these things become nearly impossible. So take the time to learn the notes on the staff and how they correspond to the keys, and you will be thankful that you did. The rest of your piano-playing life will benefit greatly.]
One of the most basic ways of learning the notes is through the use of flashcards. (click here for a good set of affordable, high quality flashcards.)
This video shows how easy it can be to learn the notes, using flashcards grouped according to the most easy to recognize notes on the staff. (If my five-year-old daughter can do it, so can you.)

Notice that many notes (in this case, 7 notes) can be written and played in either bass clef or treble clef. People tend to be confused about this. Hopefully, this illustration helps alleviate any such confusion.
