Firstly, welcome to android! Here you can find all the answers you need!
So let's get started:
1. There should be an app on the phone called "Email." This is different from GMAIL that will also be on the phone. On the Email app, you should be able to chose the type of account you have, such as hotmail, and enter the correct info and you should be golden. To check that the account is syncing with the phone, you can go to Settings>Accounts & Sync and there will be a list of accounts that you have on the phone, and which ones are syncing.
2. If Facebook for LG was on it when you got the phone, you can't get rid of it. It's called bloatware, and carriers prohibit them from being deleted unless you are rooted. This sucks, we all know, but some phones have more of this crapware than others. However, just because you can't delete it, doesn't mean you have to use it. To use FB for Android instead, just download it from the market, and sign in on it. Again, go to Accounts & Sync in your settings, and make sure that the FB for LG account is NOT syncing, and the FB for Android one is, and you should be good to go!
3. Some people argue that task killers are more counter productive. Having done an objective experiment on it myself, I have to agree with them. Best ways to extend battery life are:
-turning wi-fi and GPS off when not using it (you can control these easily by using the "Power Control" widget.
-When you ARE in a wi-fi area, like home or work, use it. Wi-fi uses much less battery (and you get faster speeds, typically) than 3G.
-Set screen timeout settings to a lower time, such as a minute.
-Turn off sync for accounts you don't use (like I described for FB fog LG) for any other accounts. Some phones' crapware is set to sync by default, like for my phone, I have stocks and news synced. So I turn it off since I never use those apps anyways.
That's pretty much it! Sorry for the lengthy reply, but I like to make sure my help is thorough. Let us know if you have any more questions! Again, welcome!
