I suggest you get a starter Astronomy book. That will help with many of you questions. There are many at your local large bookstore. Skywatching by David Levy is real good. Here's some basics. The eyepiece is a 22MM (millimeter). If you divid the focal length of the eyepiece (22) by the focal length of the telescope you get the magnification. I don't know your telescopes focal length. Most 114MM reflectors are around f/8 (focal ratio) that would make it 910MM focal length. 910/22=41, so you get 41x magnification with the 22MM eyepiece. A bigger eyepiece would get less magnification a smaller one more. Higher power gives a larger image but also dims and dulls the image. The planets and moon stand up well under high power but for deep sky objects usually a smaller sharper image is better.
