[Q] Why even unlock / boot load / roms for my GS3

Hey guys, just want to start off with an apology. I know these are stupid questions but I couldn't find an answer on the forums from searching that I could understand or that was made in the last 5 years. So here it goes.
I got a Samsung Galaxy S3 (SGH-T999) and like any new product it's stuffed full of garbage apps and bloatware. Well I want that all gone and I want full control of my device! I'm an electrical engineer, so I'm not an idiot I'm just not a software guy, so I need some very basic answers and I'll just google the rest I don't understand.
1. I know you can buy unlock codes and it lets me use other sim cards, I dont care about this, I'm keeping t-mobile for the next two years, not my choice. Does it do me any good otherwise?
2. I can install custom roms, I did this on my GS1 but it never worked out right and was really buggy. Is this the general idea of how it works? I want my phone to be as stable as possible and I want all its functionality.
3. The other apps you aren't supposed to have. I read an article in maximum PC about apps that aren't on the play store that let you under clock your CPU to get better battery life and make your phone more efficient. Do these exist, are they worth it?
4. WiFi tethering, I have T-mobile, and they want me to pay for tethering, this is bull****, if I don't go over my 2gb soft cap, then why should I be charged? If I unlock / boot load (what even is a boot load?!?!?) can I do that for free?
Thanks for the help, if you are kind enough to help me out, could you please not use short hand, I can't really google acronyms and expect an accurate result. Saves me and you time.

Tmobile samsung Galaxy question. Possible rooting help too.

Hi I had some questions, that if the action can be done by rooting my phone i was wondering if someone can send me to a video or tell me them self step by step clearly how to root a phone and if needed a custom rom with detail enough that i wont brink my phone i would very much appreciate that.
First My phone seems when on the app store to download apps really slowly, i have factory reset my phone but still acts this way can anyone help me with this issue?
Also my battery life seems to be very bad i see my phone at 97 percent one moment the 80 the next. Is the only way to increase battery life is by power saver mode and limiting my cpu and setting my brightness to nothing? or are there better options out there?
Also I was told rooting my phone and using battery calibrate might help is that true?
I have the Samsung galaxy s2 with a 1.5 cpu from t-mobile running on 4.1.2.
P.s Any other information you might know about this that will help my phone for the better please also include seeing that i have never dealt with this phone. (also i know its kinda old but with college its the only thing that really fit my budget)
P.s.s i wrote this same post on the wrong section can someone tell me how i can delete it so this isnt considered as spam or anything, would be appreciated
