What i mean is , could i shoot better with Carbon and are they more accurate ?
All bows are more accurate than the nut shooting them

.
Does carbon go out of shape like tha alluminium arrows ?
Carbons will go out of shape and the spine does weaken after repeated shooting.
Alums are straighter to begin with and are easy tostraighten if they get a slight bend.
Both have their strong points as well as their weak points.
As a newbie to the sport I would stick with the Alums as they are a heck of a lot cheaper than GOOD carbons, cause ya gonna bust some andlose some.
