We all started somewhere. I may get banned from this site for saying this but I would start with a gas or electric smoker. The heat is easy to maintain so you can concentrate on the meat rather then temperature maintenance. I used an electric for years and still do along with my charcoal smoker. Once you are used to the cooking process, have some recipes down pat, and feel comfortable with a smoker get a charcoal/woodburner and progress to the next stage in your developement.
The recipes on this site and methods described are incredible. Get Jeff's rub and bbq sauce recipe and sign up for his smoking course.
Read read and read some more on this site. Ask questions even if you think they maybe silly. You will get a good answer.
Just don't ask how much time it takes to cook something. RichT may get his underwear twisted.
Ask what temp to take food to instead. The temp matters not the time.
I hope this helps.
