2 things.
Wait until you're 16 to start doing this instead play a sport.
I don't know why these people are telling you to ignore taking care of your body.
Body and Mind go hand in hand you have to work on yourself in every area.

I'm surprised you don't like bodybuilding.com. It's the site I use and I have no problem with their users. I recommend the site.

As for advice, you are 14, so you don't need to exert yourself much. Focus on 10lb/4kg dumbbells. Mix in some sit-ups and push-ups and you should be good to go. You shouldn't have to worry about cardio, as you are very young and you say you are skinny.

Worry about muscles after you are 18, as to not conflict with your body's natural growth.

Swimming. Better than most other options and you can do it during pretty much any time of the day. Swimming is also relatively cheap and trains most of the key muscles in your body in terms of wanting to get bigger abs and such.

If you really want to look "buff", getting to a basic level of endurance before body building will get you pretty far. Most of my friends, who I consider being able to be categorized as bodybuilders, would recommend having a period of just normal training before using bigger weights or anything else. Having a good endurance overall will help you get muscle faster anyways (makes it possible to shift weights more easily between weeks).

ps. as you're pretty young, I'd skip going to the gym at your age. Not that you couldn't do it, but it's more about the grow period. If you start trying to pump all your body's grow efforts to building muscle, your growth may end up being a bit less.. Also muscles are "easily" obtained after the growth period when your body isn't trying to grow double digit numbers in cm per year.
