am i overtraining chest and bis?

i am 19 years old and weigh 200lbs. i just quit football and want be bigger than ever. i am trying new things and looking to get huge. if anyone can help, it'd be great....

incline bench press 3x8
flat dbell bench 3x8
incline flyes 3x10
decline smith machine bench 3x10


barbell curls 4x8
dbell curl 4x8
zottman curl 4x12
one arm preacher 3x10

just looking for some new ideas on chest and arms....

thats a good bread and butter chest routine.
you can always switch it up by going
barbell flat
DB Incline
DB Flat flyes
DB Decline press

i'd cut it down to 3 exercises max for bicps also, maybe replace the zottman curl with hammer
