A "split" refers to the weight-training part only. Cardio would be part of a 'rotation' that may also include a split.
You can put cardio days between weight-lifting days or do cardio before or after your weight workouts, or do a combination of both. When I'm interested in losing fat, I like to do a 12-20 minute cardio routine as an extended warm-up for my weight workouts.
As for what do do:
What are your goals?
What workouts do you have?
How much time do you want to devote to working out per day and per week? (for example " an hour a day, 5 days a week").
