For leather gloves, you only need 14 Dex w/ lightning punch + tabi, or 18 dex w/o lightning punch (can use heavy armor this way)
You could do something like this (feat chronology is messed up cuz you can't drag drop it on mobile)

If you absolutely don't want premeditation, you could remove 1 int and put it into Agi and take Uncanny Dodge, could combine with deflection if you want more dodge proc.
You could also go more beefy by taking Increased Con + Bodybuilding, although you need to remove 1 feat
If you wanna go crit, I recommend max cheap shot crit damage specializations, since fist only has 100% crit damage, although not sure if the bonus 100% works with crit power or not, if it does, then it's quite strong
If you're starved for skill point, you could shave off some of crafting skill and calculate it with Crafting Bonus, +2 INT from hypercerebrix and under pie +3 skill. Although for biology, it's better to not depend on crafting bonus, because most high-end requires Deep Cavern ingredients
Your lockpicking and hacking is also too much, you forgot to calculate the bonus using huxkey, jackknife, and lemurian engineer suit
