Welcome to IIS, Ervin. Like the others said, have fun doing visual work first up. You'll get to learn about the night sky and what things look like through your scope. Then, if you want to, you can then progress to astrophotography. Then you'll learn all about frustration!!!
Just had a look at your scope at Celestron...nice
You may want to invest in a Celestron eyepiece and filter kit for 1.25" eyepieces. Or buy 9mm, 15mm and 32mm eyepieces and a 2X barlow lens. That'll give you a good spread of magnifications. If you decide to get into astrophotos, you're going to need a more robust mount because after hanging a camera (either DSLR or CCD), guidescope and autoguider etc etc, off your scope, you'll need a good mount to handle the weight of all the equipment. The CG4 looks a little light to be handling all that. However, a small modded webcam or the Celestron NexImage camera wouldn't tax your mount at all, and you'll get great piccies of the Moon and planets.
Also, download yourself a good planetarium program, like Stellarium or Cartes du Ciel so you can plan observing sessions, create starmaps and such.
