I'll answer your questions in detail later, but first, we need to determine something here:
What EXACTLY is your current goal?
"bodybuilding" is interpreted differently by different people when they say that that's what they want to do... Some just want to get lean (or "gain definition" which is of course just getting lean... Leads to underwhelming results if there is not at least a basic level of muscle mass present)... The standard definition of bodybuilding here for a guy your size/experience though would be to get to a good size (whatever you may think that is) and then diet down to some 10% (or less if you want to step on stage).
If the latter is the case for you, then you may currently be misinformed as to how bodybuilding training is done for that purpose.
Secondly: Do you use pro-hormones and/or steroids?
That changes the game in some very important ways (esp ways to progress etc), and will influence the advice I'll give you.
If you don't want to answer that question (understandable), then my advice will be tailored to a drug free trainee between 16-30 as usual.
