I am lvl uping craft and now that i am lvl 25, i look for new place to buy items and break them but the only place i see i can buy items is on the 1º TP of dark namek map, where there isn´t any Upgrade merchant to break them. Do i have to go betewen TP to buy and break them? D:!

Yes, you have to jump from map to map... clear your bag and gogo :P
I used fear island to do 26-30, armor merchant is closer to TP :D

Ah damn it T.T
