Well, as reminder you need assign weapon rank quality for your katana (weapon rank costs 2pts per rank) and the actual official stats for katana weapon is listed in pg166. At presently your weapon has penetration and 3pts worth unique properties (or unknown really) and rank 0 = do same dmg as your base dmg modifier which is 5 with katana (unless buy attribute which increases the base dmg up).
Also if do not want boost your char further you can place remainign points to unknown power (or invest on your heirloom katana unknown power as katana has potential to be potent plot device).
Anycase so far as I can tell the char looks okay math and such wise :). Ready to go basically (just need calculate your HP, Energy, Shock Value and show the basic attack and defense values while mention what they are while using katana). Here
is charsheet section so you can see how rest chars follow the format.
