This is about where I started, so i feel you on this one.
Good, make sure you are eating a lot, but also not eating 100% crap.
Really any program will work if you are a beginner. And you can probably run WS4SB for a LONG time without having to alter it. Just make sure you stick to it. Commit yourself to one program for at least 4-6 months. Most importantly, LEARN THE LIFTS!!! <-- This will be more important than anything else that I could tell you.
Don’t think of this in a way in that you are going to ONLY work out for a time period, and then be done. Getting bigger and stronger is a day to day task that will last years, and it is one where you will never be satisfied. If you want me to tell you that you will look perfect in 6 months, it would be a damn lie. You will most likely progress in 6 months, and that’s about all that matters, PROGRESS.
Also, don’t feed me that bad genes bullshit, because genes aren’t the issue. I started off very similar to your current stats, and i have made a decent amount of progress. The only excuse you should have in your arsenal is that YOU at the problem, not your genes.
Otherwise your attitude is going to kill any potential progress you may have.
