How much data is 1GB for Iphone 4s?

I just got an iphone thats in a plan with 3 other devices (moms ipad&phone, and sisters phone). There are 4gb that we all share (so 1 gb for each device). I don't go on twitter or vine, facebook, etc very often on my phone since i have laptop,
is 1gb a month enough for me to leave my data on (i plan to turn it off at night) so i can receive imessages from my friends and text them?

How to permanently delete photos off of iPhone 4s?

I'll delete photos off of my iPhone, and then when i plug it into my Mac, all the deleted photos sync to it. Also, my iTunes says there's 2, 600 photos, but my phones camera roll says 1, 500. How do I permanently delete them? I've heard that you need to delete them from your computer, but how do I do that on a Mac?

Added (1). The sync photos box has never been checked.

Need advice getting something i really want?

Okay, well my mom and i were going to switch to a phone service carrier because she thought that it would be cheaoer then the one we had now. I had planned out getting allowance specifically so that i could pay for my phome every month. I'm getting an iphone, and i have been wanting one for along time so i really want this to happen
I have been working on this whole idea for almost a month and when my mom said yes, of course i was really happy. But then yesterday me and my mom got in a fight over something stupid and i got mad so i started being and acting super immature and finally my mom said that was it, that we werent switching carriers and i wasn't getting my new phone
I would of asked for another chance, but something similar has already happened before and she gave me another chance. I haven't talked to her about it since we have sorta made up, and i'm willing to do anything to fix this so we can still go through with it, since i'm pretty sure we will be switching next week.

Any ideas what to do?
I already told myself that to try to fix it i was going to listen to what my moms says and do it and continuewith my chores so i can still get allowance and pay for it? I also want me and my moms relationship to go back to the way it was yesterday before it started.
Thank you and full points to the best answer.

P.S - sorry for any typos i'm typing on my phone

My iphone and itunes have up to date software and this past time when I synced my phone some songs that were already on my phone now skip and show the still downloading circle and songs from my new CD won't upload to my phone at all. I've tried restarting the phone, deleting/readding songs, etc and nothing has worked.
