It's only necessary to post a question in one category.
It sounds like you already have a high metabolism.
At 135 pounds, you should definitely bulk up, which is done through eating like an animal and training like a beast.
www.startingstrength.net , that's a good program for beginners to get their foundation built, I would just replace power cleans with barbell rows so that the shoulders remained balanced (ask if you want to know how rows/benches balance the shoulders).
If you don't like it, google "Push/Pull/Legs".
Healthy foods are the key to hypertrophy (size), the first thing we'll do is get your nutrition set. It's not hard to follow a strict diet with the help of protein shakes. 3 meals per day and 2 shakes per day is what I do, I get in plenty of calories and even exceed my calorie expectations.
Give us a look at what you usually eat, we'll critique.
Also, if you're worried about volume (reps/sets). 3 x 5 is good. But here is something I usually recommend to beginners.
3 x 10 until you plateau (increase by 5 lbs each week)
use that same weight the next week with 3 x 8 (increase by 5 lbs until you plateau)
use that same weight the next week with 3 x 5 (increase by 5 lbs until you plateau)
use that same weight the next week with 3 x 3 (increase by 5 lbs until you plateau)
use that same weight the next week with 1 x 3 (increase by 5 lbs untill you plateau)
when you plateau.. go back to 3 x 10 with the 5 lbs less than the original plateau weight and you should have busted it.
