OP, for the time being skip posting in the forums where you obviously have a hundred questions and you will inevitably get a thousand different responses.
Instead, focus your time on reading articles that will provide you a general consensus on the direction you need to head in with your training and diet, because right now both are terrible.
This will allow you to learn the basics and develop a solid foundation, so you can then ask specific questions (which btw should be posted in the Beginners forum, since you are in fact a beginner) that can be more directly answered . Have you even read the stickies yet in the Beginners forum? That’s where you need to start…
The two following Nate Green articles will probably be useful for you as well:
