I lost my house on minecraft? - 1

I went on a quest to find sheep and next thing I know I'm running around with my head cut off for 6 minecraft days and night trying to find my house! It was near a really deep canyon and I'm close to mountains! D: Is there anyway to find my house? I don't want to die so I respawn closer because I have a TON of stuff, I could put the stuff in my chest that I have but, I'd never be able to find the chest again!

Minecraft setup on MacBook Pro 13 2.4 ghz?

So I'm getting a MacBook Pro 13" 2.4 ghz and I'm going to buy minecraft on it. I was wondering that how do I install it like I heard it needed java or something so will I have to download that first or will the Mac come with all the requirements and all I have to do is download the Mac version on minecraft.net?
Please DON'T RECOMMEND/TALK ABOUT OTHER LAPTOPS
thanks in advance.

Added (1). Let me rephrase, thank you very much.

Do you need to download and install java before you download/play minecraft or is the MacBook already come with a built in program like java therefore you won't need to install java?

I'm aware that on minecraft.net you can also download a Mac version therefore do I just directly download it (Mac version) or will I still have to install other programs (java and whatnot) to be able to run minecraft on my MacBook (for the Mac version download)

Sorry if it's a bit confusing for some

Why won't minecraft download?

How to buy minecraft with my current account?

I have an account on minecraft website for sometime.

I decided now to purchase the game. The problem is that I click on the "Get Minecraft" button and it redirects me to a page where I should make a new Mojang account or use my current one. When I choose to use my current account it tells me to put e-mail address and password.

Good as far as here.

Then, all of a sudden, my username changes to my e-mail and when I try to put a minecraft name (the name of my previous account) it says it already excist.

Any help?

Added (1). If I make a new account, I can't choose my previous name as the Minecraft display name

Does a gpu make stuff load faster? Or just display smoother?

I don't even have a GPU.
I use onboard graphics. Intel hd 2000.
But my friend got a new gpu so he's gonna give me his old one.
And I'm just wondering if I would actually notice anything different using the gpu instetad of onboard?
The gpu is evga geforce gt 630.
I mostly just stream youtube videos in 1080p but sometimes I play games.
None of the games are really graphics intensive though. Minecraft. League of legends and DOTA 2.
And I use Windows 8.
Will I notice anything better using the gpu?
