I just started playing pen and paper RPG,s and the first game I bought was dark heresy, and I was hoping for any tips or resources that this community can provide. I am the GM.

Well, take a look at the site in my sig. It's got tonnes of Dark Heresy/Rogue Trader stuff on it.

If you are a first time GM, do not try to create a campaigne . This is like starting to play american football and trying to start playing in a major league team.

Start with published material, modify them as you like, create linked sessions...but do not try to create a campaigne. Rom wasn´t build in a day. And at the beginning, the founds where only trying to make a city, not a world spanning empire

Allow me to respectfully disagree with Gregorius12778. There is no reason, even as a first time GM, that you can't create a campaign. A few tips...

1. Get to know the rules. Read the rule book and get a feel for the basic mechanics of the game.
2. While your playing the game, don't worry about getting every rule exactly right every time.
3. Start small, with one adventure. Either take something prewritten (you can buy adventures or find some good ones online) or create your own. I find basing adventures on favorites movies, tv shows or books is always a good way to start.
4. For a campaign, once you've finished your first adventure make a second one. When possible, include non-player characters from the first adventure in the second... recurring villians are great, but recurring bit characters are great too, providing a sense of continuity and depth to the game. Just build each session on the last.
5. Most important, have fun. As long as you and your players are having fun you are doing it right.

Those are some general tips. If you've got more specific questions, you've got a whole forum full of people here who will love to help you out.

the best tip i could possibly give you is to listen to your players sometimes there theories turn out as better villains/plot seeds than the ones originally intended or be a great resource for ideas for future scenarios

My first three games of Dark Heresy were all scenarios that I wrote, and while the third one wasn't the most successful game in the world they pretty much all worked fine, with the second game being a complete blast.

There's nothing wrong with writing your own campaign to start with. What I will suggest though is that if you have a killer idea for a campaign, don't do that first. Start small with little scenarios and whatnot, and once your players know the rules, then use your good ideas. No sense in wasting a good campaign idea because when everyone is too busy trying to look up rules to be bothered with the plot.
