is this for a home game or a PFS game?
Can you elaborate more on what you're wanting to do?
You're gonna have to be WAY MORE specific on what you want to do here and why.
Is this for Pathfinder Society? You can still change a character however you'd like while still level 1. If only using materials from the Core Rulebook, don't actually need the Core Rulebook as those are standard rules assumed to be available to all, but need to own any books for materials used outside of the Core Rulebook. Not sure why you'd need a computer. Or print outs?
If this is for a home game, ask your GM. Still not sure why you'd need computer or print out.
You cannot change a character in the Pathfinder Society campaign after youve reached level 2.
If youve registered the character it cannot be deleted either(to the best of my knowledge).

You can retrain some things, but not others.
In the Pathfinder Society its possible to retrain, but it requires Prestige and a GM to authorize it. It prevents people from swapping things out from game to game.
Didnt know you could retrain racial abilities, but it takes 1 Prestige point per day and 20 days, so its unlikely you will have 20 prestige to do so.
Confusing but both the abilities races have naturally and a specific type of trait certain races can take are both called "racial traits". I separate them in "ability" and "trait" to avoid confusion.
it for pathfinder society i am a lvl 2 elf ranger> i am trying to change the racial traits of the elf thats all. thats way i printed out what the changes are
Have you played the ranger as a level 2 character yet?
Where are these changes you "printed"? List it out and others can tell you what the possible options/costs are if required to use the retraining rules from Ultimate Campaign.
Still got no idea what "change things on a charecter with out the book are computer. can you use print outs" is supposed to be asking for.
