Can anyone give me any tips with lightning? I feel like these are coming out really dark I'm using two spotlights, are there pre set lighting settings I can download or render settings I need to adjust?
While I totally agree with many of the examples given to you already, I am going to highly recommend there IS a pre-setting lights asset you can download that will make your learning of creating your own individual lighting much easier. Go download this:

It will load presets for closeup portraits and full body renders in many different varieties, both using different recommended angles and light settings.
The reason I recommend it for you is that there is a teaching principle that every educator/teacher knows (I have 2 teaching degrees). You "Teach (learn) from the Known to the Unknown". DAZ Studio is way complicated for new users. You will get extremely frustrated trying to figure out "good lighting" if you can't even create/move the lights where you want them (or need them) to be in the first place. Or if you can't even get a "standard" 3-light scenario configured to start with. Boss Lights will do all of that for you with a single mouse click for a variety of lighting scenarios. THEN to learn what different light SETTINGS for each light will do is simply a matter of changing the parameter for any of the lights and seeing what the result is (as others said, turn off the Dome and Headlamp lights and use only the Scene light in the Render tab). You can enable/disable any, some, whichever light(s) you want in the Scene tab to learn a variety of "light combinations". Also change intensities, colors, etc in the lights settings (either the Parameters, Lights, or Render tabs). Once you grasp how the different POSITIONS and SETTINGS of the lights affect a scene (the Unknown for you right now), THEN you can go about learning how to create/move your own lights for a scene. Using a preset positions the lights for you and starts you at a "Known", then allows you to play around with the settings and progress ("learn") towards your "Unknown".
There is nothing wrong with using a pre-set of lights to learn how they work. Start with a preset ("Known"), then move on to learning how changing settings, etc affects things (your "Unknown" right now). I've only been rendering for about 2 months, and initially trying to figure out light positioning, etc, on my own was a nightmare. Then I installed Boss Lights and by just playing around with the "already installed for a scene" lights in it, it was literally like "The lights went on in my head!" about how to do it.
I have no connection in any way with the development or author of Boss Lights. I'm just recommending what a good teacher would tell you to do in your case. The instructional videos others have recommended will even make a lot more sense after you have played around with Boss Lights and got a feel for it. Note Boss Lights is for "studio" type lighting. Other lighting scenarios (outdoors, full room lighting, etc) will require different methods like the ones other have mentioned. But your post included a "studio" type render, so use Boss Lights to help learn how to do that kind of lighting.
