As for an actual critique, as an Ork and a primary combatant, you are missing out hugely by not taking advantage of your naturally high BOD and STR. I get that you're doing the cyberlimb thing, so you can probably skip out on the STR (though you should just drop it to 7 or bump it up to 9 - this is when your DVs change), but you should definitely bump your BOD up to 7.
Regarding skills, you have taken 32 BP worth of Skills from the Stealth Group - though you only have a 4 in two of them. If you can scrounge up 8 more BP you could have 4s in all 4 Skills.
You appear to have broken multiple rules regarding Martial Arts. You only have Arnis de Mano Rating 1, however you have 3 Advantages, you're only allowed 1 per rating, you are also only allowed 2 Maneuvers per Martial Art rating, you have 8.
Some GMs may not allow 2nd-Hand Alphaware as I think the whole thing with Alphaware is it's tailored specifically for the person who buys it, may want to check on that before committing to it... Also, not a big fan of 2nd-Hand 'ware in general, it's a better investment (i.e. you don't have to re-buy everything later) to just get less stuff IMO, but YM(and GM)MV.
Considering that Logic affects how quickly the character can learn, that definitely makes a Logic rating of 1 seriously mentally impaired.
How easily distracted one would be would be a function of Intuition.
Difficulty learning does not necessarily equal mentally impaired, so sorry. I have friends that aren't good at book learning but are brilliant chefs or businessmen.
p. 67, SR4A - "A Logic-lacking character might get overwhelmed when confronted with a lot of details and may have a poor memory" close enough to easily distracted in the context of Reason and Learning for me
