Okay, lets see. Questions...
Shayuri: The standard language throughout the Imperium is Low Gothic. Local accents and pidgins might make it unintelligible. High Gothic is spoken by nobles and on Earth. Tech Priests are commonly able to communicate in the language of machines, Machine Speech (R2-D2 speech).
Inquisitors tend to be good at everything as they're the cream of the crop as agents go. Good Attack/Defense/Saves/Skills, in general. Athletic skills, social skills and stealth skills, along with some knowledge skills should serve you well. Note, a top-grade bounty-hunter or commando might be better at combat than an Inquisitor, but the Inquisitor has other skills (and isn't a one-trick pony, usually).
Drerek: looks good.
Its kind of an oxymoron, but the Mechanicus is all about preserving ancient knowledge and worshiping it... actual invention of NEW technology is heresy/blasphemy; so, if you're not a heretic/radical, your invention ability will be more about knowing technological tricks that no one else knows about (aside from other tech-priests) than inventing brand new things.
Eltharon: From what you write it sounds like a simple Interrogator, albeit one focused on combat/assassination, would work for you. An actual assassin would also take a whole lot of points (though possibly less than a space marine though they are, technically, more powerful). If you're dead-set on the assassin route, maybe a death cultist might be better. They're not quite as good as assassins (in that, they're not designed to replace sending in thousands of Imperial Guardsman) but they're still considered quite deadly (fearless close combat monsters).
