What to improve on

I'm a 147 DB, but like everyone else, I feel as if I should improve.
I have the following equips:

Clean CZak, Epic 3line; 3% allstat
6% Luk 3lined Rex earrings
3% Luk Reverse DB mask
4% allstat Specs
12% luk pirate top
HB pants with 6% HP and 6% MP
3% luk shoe
14 atk WG
4% luk 3 atk PAC
3% Allstat HTP
Evo Ring Lv 11
Evo Ring II lv 17
Last UWG ring
Angelic Blessing
PvP Belt
PvP shoulders

135 Pescas, with 4% crit and 12 atk on potentials
82 atk katara, 6% damage

I have about 25k NX that I'd like to use on improving my range.
