Is it possible that I can have one of the largest Mining and "Planet Resource Exploration" firms in the whole universe or?

I don't know, that depends. Is your corporation mining with cheap slaves and advanced technology, with the demand that's required of a empire that's aiming to gain more ships, research new technologies, etc., rather than just make a profit? 

An autocracy or other government-controls-all faction would likely be more invested into getting their own materials, when they've never met another decently powerful spacefaring race. A corporation catering to aliens wouldn't be very profitable- not yet. It'd have to be politically involved, and with its mother nation supporting and offering the corporation's resources to trade for other things.

Speaking of which, the first few Star Empires always had someone getting a little tidbit of someone else's technology... and then reverse engineering it very, very quickly. No fun when someone just buys one, and then makes their own shortly afterward, now is it? 

Gonna have to make some kind of Galactic United Nations or somesuch, to help protect that kind of thing, keep one person from just reverse engineering everything and making their own.
