Hi, I'm 17, and I'm fat, but don't want to be anymore. I know, more excercise+eat right.

I'm 6'1.5, and 247, 26% bf.
lean weight 181, normal cholesteral and blood pressure.

i really want to get down to maybe, 15% bf, is that possible by the end of the summer? i have a total gym at home, and some dumbells. I have recently started running, and have notcied some loss already.

I also wanna get stronger. my main goal is to be able to do a pullup/chinup, whatever. never been able to one my whole life.

also, whats the best muscles for arm wrestling? i know it probably sounds triveal, but my friend, 5'10, 150, RIPPED, not jacked lol, but ripped, can beat me, and it annoys me lol...

also, i like being bigger than my friends, so is can i loose fat and gain muscle at the same time?

how much proetin should i be taking in, do i need to take a suppliment?

sry for all the questions, don't mind if u get technical, i took AP bio...

thanks!
