What does all this rooting mean lol?!?
Is that something I have to do or is it optional? This is my first android phone you see...so no nothing about all these things!!!!
Rooting is equivalent to administrator access on a computer; it allows you to modify/change nearly anything on the phone. This, combined with an unlocked bootloader, allows you to put a custom recovery (pretty much a menu that allows you to install custom software onto the phone to replace manufacturer software, such as putting stock Android onto a phone like the G2 that normally comes with LG's custom UI) onto the phone allowing you the ability to change everything about your device, for better or for worse.
In most cases, you'll be fine with just having root capabilities as this will allow you to change the interface, remove bloatware, and use root apps such as ad blockers. Rooting, in most cases, is very easy and cannot harm your device. Installing a custom recovery/custom software (known as custom ROM's) onto your device is more dangerous, but is also very easy once you get the hang of it. Hell, I taught my 38 year old cousin—who was new to rooting/ROMing—how to do it to his Nexus 4 in a few days and now he switches between ROM's all the time. It can take time to learn, and there's a lot to read up on, but it's very fun and interesting and can allow you to get the most out of your device.
For me, this means being able to put the best ROM on my phone that will give me the most battery life. On the G2 with the stock LG ROM I can get about a day's use out of the phone without having to recharge it, but if I put a custom ROM like CyanongenMod 10.2 (usually referred to as CM10.2 for Jellybean (Android 4.3) or CM11 for KitKat (Android 4.4)) I can easily get my G2 to last two days on a charge while also offering better performance. Some people may instead prefer a different ROM, and there's tons to choose from.
If you're interested in learning all of this, the G2 will be a great phone for you to start learning with since it has an easily unlockable bootloader, an active and growing development community (see the LG G2 section on the XDA-Developers forum), and tons of custom mods, ROM's, etc. to choose from. If you're not interested in learning this, then the G2 is still a great device to choose! Contrary to what most people think, the stock LG ROM is great. It offers tons of customizability out of the box, has tons of features, and offers great battery life. If the buttons on the rear of the device don't bother you, you'll love this phone.

I have just got the LG G2....
How do you get rid of one of your home screens?
----------
How long do you get? I just got my G2 today....
Also does anybody recommend a case?
I believe you pinch the screen in (or out) to view all of your home screens and from there you can remove or add them. As for a case, I've heard good things about the Incipio DualPro and have just ordered one for myself.

I just got this phone on a contract with 3
How do you get rid of the apps that came with the phone like ebay....or is it installed and cannot be removed?
Also are there any apps that you recommend to download or anything you should do to save battery on your phone?
If you go into Settings->Applications->All Applications, you should be able to either disable or uninstall those apps. Disabling them stops them from running/wasting battery. If you can't disable or uninstall them then the only way to remove them is to root your phone. If you're interested in rooting and need assistance, I'd be happy to help; just send me a PM. Same goes for anyone else who wants help with rooting.
For battery saving apps, I've heard good things about JuiceDefender, so you might want to check that one out. Personally, I don't use any battery saving apps, though, so I'm not of much help in that department. Maybe someone else can chime in with some suggestions.

I sold mine a while ago. It's a phenomenal phone and also having owned the Nexus 5 I think I would choose the G2 over that ONLY if the G2 didn't have the rear placed buttons, which eventually wore me out. I was hoping the Nexus 5 would have been a G2 without rear buttons, but it was different enough to push me away.
I'm not the biggest fan of the rear buttons, but that's only because the ones on the Verizon model REALLY suck. On the plus side, there's cases that are supposed to help with this issue such as the Incipio DualPro which add individual ridges and bumps to each button so I'm hoping that'll be enough for me. I do have to say, however, that LG should've just stuck with the buttons on the side. Would've made this phone perfect, IMO.

eek
Personally I'd only push the android savvy to the G2
IMO Root & Rom are almost required for the G2
If you want to learn, find your device on xda-developers.com and read, then keep reading, and then read some more.
I'd say the G2 is a great phone for everyone. It comes with top of the line specs, an amazing display, awesome battery life, a great camera, and a highly customizable UI on top of all that. It's also a great phone for those who are interested in the development scene, such as rooting and ROMing.
