1: Sadly not, I very much suggest checking Faiter's or Axiege's let's plays of the game, both can be found on the general discussion page. Personally I believe you will like the game. I dumped $10 on it back in January hoping it was the game I thought it was, I have since spent more time playing it than any AAA title, Ever.
2: The game as it is now is very incomplete, its lacking exploration, trading, and industry. ( i don't think industry is planned to be tedious researching)
The game currently contains only combat and things to enhance combat, such as the customization of your fleet. ( weapons and abilities, no unnecessary paint jobs or stat numbers to track) As of now the campaign consists of a large solar system with a few planets and space stations, you can fly about an interact with the 4 factions of the game, lawless pirates, The brutal Hegemony, greedy Tri-Tachyons, and independent independents. By interact I mean get yelled at mostly ( the captains in the game aren't the best conversationalists yet.) and fighting them of course. Each faction uses different ships, pirates mostly use whatever they get their hands on mostly low end low tech ships. The hegemony use low tech but very powerful ships and on the opposite side the Tri-tachyons use very high tech ships and weapons on their high end ships, and the independents are somewhere in the middle. Each faction tracks your relationship to them separately, and all ( but the pirates) start neutral to the player, however it only takes one fight with someone to turn them into an enemy, and as of right now there is no way to make them friendly again. If you attack the TT, Hegemony, or independents all their fleets will forever become hostile to you and chase you if they think they can beat you in a fight, or run away if they think they can't. Fighting the major factions is not a recommended course of action right off the bat, i'd wait until you amass a few credits a decent ship and some skills.
At the beginning of a new campaign you also get to create your character which will stick with you for that entire campaign ( They currently do not end even if you are utterly destroyed, you get restarted with a basic ship and loose a lot of stuff.) you can orient your character in a few ways, focusing on single ship combat, leadership skills, or benefiting all the ships in your fleet including your own. Or any combination thereof.
Outside of the campaign you can play a set of missions designed to challenge the player, some more than others.
Lastly welcome to the forums, enjoy your stay.
