Hi Shacky and welcome
I started out with a 114mm Newt on an EQ mount as well! It gave me some memorable nights, and showed me my first DSOs. I still use it for dedicated solar observing, with a JMB full aperture solar filter.
Here is some info on different types of eyepieces, as well as some important basics for beginners:

Good luck, have fun.
