you'll need them.

if you compare a 1* item with the same piece but 2 or 3*, you'll notice the 3* items have the best stats, but are also the most rare.

all can be crafted, but 3* are the most rare.
1* items drop from regular mobs
3* can drop from bosses.
not sure about 2* >.>

there are also items with yellow/golden stars, which were made of molds (=special material, boss drops, very rare and expensive)

and green star items which are made from tt materials.
(tt means twilight temple, that's a lvl60+ dungeon / some people call it hh)

the +x behind the items name is the refinement. the stats get better the more something is refined.
