First of all, I'm going to say that it looks like you've captured the basic playstyles of each class fairly well. On the other hand, the optimum way to play physical dps might actually change from lower levels to endgame depending on your gold investment.
KP in Attack Speed is useless. Attack Speed as a stat is great, but the KP is largely ineffective since decent and great Attack Speed can be attained without investment in the KP.
Crit Dmg depends on your [endgame] gear, certificates, Legendary Achievements (up to 15 points of extra Crit Dmg/M-Crit Dmg from these), heroic trait, and glyphs. Count up all the Crit Dmg you'd have with your ideal set and invest accordingly.
Thief can easily be played for Attack Speed/Eva or Crit builds early in the game depending on which armor you use, but either Crit Dmg will be lacking or both Attack Speed and Eva. Later in the game, most Thief players are able to overreach earlier limits and hybridize either from Atk Speed/Eva and gain Crit or extend from Crit and incorporate Atk Speed and Eva into their builds. It feels like you're sliding around on a spectrum and when great gear is available, you can achieve sort of a balance (however, you're still more inclined towards the armor type you base you build on).
Thief is somewhat difficult to build properly since people want varying amounts of Crit, Eva, and individual skill boosts, though at least 10 points in Crit Rate is probably a safe bet. I personally put KP in Blend since I like that it is infinitely renewable as well as in Gallop and Cruel Slashes for stealth style burst damage. Some players prefer not to rely too much on the stealth stun, though, since it's annoying and sometimes risky to use. Some people who use Dagger + Shield for Block on top of Eva might consider Dagger P-Atk/M-Atk.
Martial Artist is more straightforward. 15 levels in Crit Rate, however much Crit Dmg is needed, then either go high in Cestus P-Atk/M-Atk or invest in Str. Str gives less power than Cestus mastery, but it increases Block Rate with a Shield, which is becoming increasingly popular as an endgame playstyle for physical dps. The Charging boost is not worth it due to heavy waste of KP in Atk Speed as a prerequisite, and the buff itself is powerful enough. Although MA may seem less Eva oriented than Thief, using the same armor a Thief would use for bulk grants MA quit similar bulk, and more Block with a Shield.
Attack Speed really takes off past level 60, and especially 65 for dps classes to use. Thief is able to maintain decent Atk Speed at earlier levels unbuffed, and MA can do so with Charging. Later in the game, accumulating bonuses to Atk Speed via using an Atk Speed pet, completing Legendary Achievements, using the Ranger (yes, unlock Ranger and play it for this) certificate for 15% flat Atk Speed, and the Ice Meteor lets one have very decent Atk Speed unbuffed from the start. Don't focus on this now, just keep it in the back of your mind for later.
