Gyms are worth it if you can get through even one Pokemon; you get XP for it. But you probably don't want to try for gyms until you're level 10 or so.

Don't waste your stardust on powering up Pokemon until you're past level 15. As you level up, wild Pokemon will show up with higher CP, and odds are that you're just going to level up and get a new Pokemon with better stats than the one you spent stardust on.

In general, don't bother trying to catch evolved Pokemon right now unless it's something particularly rare that you need for Pokedex completion. With the capture rates being what they are, you're going to waste a lot of balls on them and they're not worth any more candy than the unevolved form. I mean, if you see a Ninetales and you can't even find a Vulpix, then heck yeah catch it, but that's the general idea.

Bluestacks is just an Android emulator. If you want to give it a moving, fake GPS location with the arrow keys, you have to install an app to control that and set it up, because the default configuration doesn't do it.
