Questions about first build

[Garthoro]

This is my first build and I'm planning on getting this components http://pcpartpicker.com/p/3XFCf7
So the questions:
1) Is this build good for gaming and video edition? Will it run games like GTA V? (I don't care if it's low or high resolution)
2) At home I have wireless connection, do I need to get something for the computer to connect to it? If this is right, can someone recommend one?
3) Is it hard to build a computer, this is my first build and I'm not sure if I should build everything myself (by watching videos) or get someone who knows how to make it. If you guys say I should do it myself please if you can give me some tips would be really apreciated.
ps: anything I should change in the list just say.

1. Yes
2. Pick up a USB wireless adapter
3. No, my kids were 5 and 7 years old when they started and there are plenty of video for help as well as many, many members here that will help if needed

2. What USB wireless adapter should I choose? I want it to work the best possible
3. Any tips? I saw on internet something about touching metal for the motherboard.
Thanks for the fast answer

For a USB wireless adapter, I'd get at least a N rated, not sure of budget, the Asus USB-N13 is good (about $25), Rosewill RNX-N180UBEv2 (about $20), Linksys AE3000-NP ($40ish), Linksys AE3000 ($50ish)

You can get a grounding strap, or simply touch the case or PSU as you go to discharge static. I don't build in carpeted rooms is a good hint.

Two more question:
Is this PSU better? https://pcpartpicker.com/part/evga-power-supply-120g10650xr
I was reading comments about the seasonic and I saw that the cable that goes to motherboard was a little bit short which made me freak out a little bit (quite nervous, first build) and I also saw this one was 80+ gold and fully modular.

And the second, is it that risky to go with the components on a backpack in a plane? Because I'm not from US and my mother is going there, and I'll ask her to bring the GPU and maybe some other components, so I wanted to know if it was too risky or if what components should I choose that are non-risk of breaking on the plane.

That's a good PSU, yes - on the components, I'd box them nicely and with some padding and check through as luggage

"I'd box them nicely and with some padding and check through as luggage" is this safer than taking it on the plane on a backpack? Idk I was like quite scared of the PSU breaking when they throw the luggage to the plane and from the plane.

Could take the PSU in a backpack, they may want to take it apart to ensure it isn't a bomb - I'd check with the airlines and security. If boxed and marked fragile, should be OK or ship it FedEx - i get things fairly often from China and Taiwan and never had any problems
