Needing some things appraised

[Noob]

I have the following, and I need to know how much each is worth:

Snapchat: zen
Instagram: vey
Xbox GT: wh*ck*r (Hint: i Ate a stEak)
6 year tenure with 30k gamerscore, decent dlc, Xbox live until 7/27/2016
3 letter GT, which is under a parent lock but can be removed

On the 3 letter with parental lock, do you have the parental account info?

I have the email for the parent account, not the password. I've heard persuading the Xbox customer support guys to change the parent email associated with the account is the best way to remove it
