How to start learning acoustic guitar?

I'm planning to learn the acoustic guitar, but I have trouble getting in the right direction. Sadly, I don't have enough money for guitar classes, so the internet is my only option. Anyways, any suggestions or tips/warnings/supplies I need? To help me on my instrumental journey? (By the way, I already have a guitar-- Jasmine by Takamine? I don't know if that's a proper learning guitar for beginners like me, but my father had gotten it and it was just sitting in the attic. Only recently he got it tuned-- maybe a few months ago so I don't know if I tune it again?)

IPhone 5 charges really fast but loses battery life fast?

I have an iPhone 5 with the iOS 8 but since I updates to iOS 7 the battery started to lose rapidly. It would be on 100% in the morning and at about 11 would be down to 40%. It would also only take 2-3 hours to fully charge and I think that's why it's losing power so quickly. Is there a way I can stop that?

Weird problem with iTunes? When I sync, doesn't show All my song files?

I have synced my iPhone with iTunes with no problems so many times in the past and on my computer it has all the same files that are being transferred onto my iPhone from iTunes exactly (this includes all music, videos, etc.). But I just opened iTunes and now it only shows my iCloud music purchases. All my other song files that I downloaded and put on iTunes are gone from my computer. However, all of them are still on my phone but if I sync, it will delete all the songs not showing on the iTunes list. What do I do? Is there a way to recover my original library with all the songs (I have around 600 songs in my library, but this one only shows my iCloud song purchases, there's only like 10 of them)
