You can see what league you are in by looking on that small nearly triangulated shape on the top left corner.

Older base pic of mine. You can make it bigger by clicking on it. So, my league is that grey thing with a I on it, means I'm in silver I.
The four-digit-number next to it shows my count of trophies. You gain those by winning defenses or attacks and lose some when you lose either a defense or an attack.
With maxed th8-troops you should push to either silver I or gold III/II, but I guess you didn't even do some laboratory updates yet, right? Start getting up archers first, second barbarians, third giants, fourth wallbreakers. Then upgrade lab and do the same again until those are level 4/5. You don't need the other troops for farming in the beginning.
For barch-attacks you choose on what's outside in the collectors and empty those. Just read the guide, I think it explains everything pretty well.
Can you post a picture of your base?
