To sign "eraser," hold your non-dominant hand flat in front of you with the palm facing up, representing a piece of paper. Form your dominant hand into an 'A' handshape, as if you are holding a small eraser. Rub the knuckles or heel of your dominant hand back and forth across your non-dominant palm a couple of times.
Sign "you," "have," and then the sign for "eraser" by rubbing your dominant 'A' hand across your flat non-dominant palm. Remember to raise your eyebrows to indicate a yes/no question.
Sign "I," "need," "buy," "new," and finish with "eraser." Make sure the rubbing motion is clear and uses the 'A' handshape to distinguish it from similar signs.
Sign "please," "give-me," and then "eraser." The motion of your dominant hand should briskly mimic rubbing out a mistake on a piece of paper.

No, this specific sign—rubbing the palm of your hand—is used specifically for a pencil eraser on paper. If you want to sign a chalkboard or whiteboard eraser, you would mimic wiping a vertical surface in the air in front of you.
You should always use your dominant hand to perform the active erasing motion, while your non-dominant hand acts as the stationary paper. If you are right-handed, your right hand moves; if you are left-handed, your left hand does the rubbing.
Usually, two or three quick back-and-forth movements are perfectly sufficient. The goal is simply to clearly show the action of erasing without dragging out the sign unnecessarily. Keep the motion brisk and natural, just like erasing a real mistake.
