Need guidance

Hi
I have started workout a month ago.
I am 26 yrs old with around 5'10".

What I want (in me) is
- Broad look/shoulders
- Straight chest (means not big like wrestlers)
- Good big muscles in shoulders, arms area.
- Good shape body

Whats I am looking for is
- Good plan (excercises, reps etc) for 3 days a week
- Some diet requirement guide/suggestions

Would highly appreciate if you guide me &/or
refer to some site.

Thanks
