Few Questions, Help a brotha out

[RapCapital]

First off where do i go to Center/Change Size + Italisize the Username + Title Like That in the Screenshot?

Then how do i add a Custom Profile Field to be VIEWED under your name like The Nickname One, Not just in your Profile.

And how do i put "REP:" beside the Rep Points like that, On my board it just shows the Icons for the rep and doesn't have "REP:" Beside it, Also how do i give REP it's own Table,

THANKS YALL!
