Need help with a certain hairstyle (male)

first off from what i can see your hair looks soo much better but if u want i think u could do it pretty easily with a curling iron bout 1in diamiter ad just curl the ends

Here are some pictures of my hair right now (face is drawn over because of parents' paranoia):




To describe my hair: the hairs from my forehead grow down till about my jaw, and the hairs that are furthest down grow to my shoulders and curl a bit. If you look at it from a side view, it looks really flat and sort of curves out towards the bottom.

What I want: A Bucky Covington (from American Idol season 5) hairstyle. I dont want to dye it blonde, and I do realize that he's pretty...ugly, but I really really like that hairstyle. For example:






Now I'm sure that his hairstyle is not regularly like that since his is really thin and really similar to mine:


So, how would I go about getting my hair like that? To be more specific, here are better questions:
1. How long will it take to grow my hair out that long from what I have right now?
2. Once it is at that length, how should I go about waving/curling the parts of my hair that need to be curled? What parts should I curl?
3. How would I add more volume to the back of my hair rather than having it being flat?
4. How would I stop it from curving towards the bottom (look at the lower part of my hair in picture #2)?

Please help me. I really will appreciate it. Thanks!
