Need some weight lifting help/tips please.

So for the past year I would just do little workouts at home bit lately ive been getting bored of that and wanting more so I joined the gym. I still have to lose approx 60lbs normally do about 30-45 mins of hard cardio or up to an hour depending on how much time I have for myself. So my main question is im not sure what to do on the weights. Like should I split up arms, legs, and shoulders to just focus on one per day to let the other rest? I dont know any of the pro's, con's, do's, and don'ts. Any advice will be much appreciated
