Time for me to jump in here (andhopefullynotscareoffthenewguyagain). Be warned that what I'm about to say may have been already said above but I want to give you some pointers.
-Don't think too highly of yourself. Your first tracks are going to suck, and that's fine. You'll get better.
-Learn how to react to criticism. Don't bash criticizers, listen to them even if they're haters. If they start actually flaming and personally attacking you, ignore or block them.
-Learn theory, and learn it well. Even if you think you don't need to, it will help you greatly.
-Look for critique. Many people aren't going to leave good, thorough critiques unless you specifically ask them to.
-In the same vein, don't just listen to youtube or soundcloud comments. Especially once you build up a following.
There's a lot more I could post but I can't think of anything. Oh yeah, get to know people around here if you plan on sticking around. Try posting in the spam thread - I'm too lazy to grab a link but it's always near the top of the Community subforum (or whatever the hell circuitfry decided to call it now). Just be nice.
With regards to dubstep, the "upbeat and fast paced" style of dubstep is called drumstep, a portmanteau of dubstep and drum and bass. A portmanteau that incorporates a portmanteau. Odd. Some facts about it:
-It's in the 150-180 BPM range, give or take a few, whereas normal dubstep is generally 140 with halftime drums.
-It will be too hard to make for you. I don't mean that as an insult, but you will literally be unable to make anything decent in the genre for quite some time.
If you're going to learn any type of synthesis, start with the basics. While many growly and squelchy basses are not made with the common subtractive style of synthesis, learning subtractive synthesis is a must. Once you've well and truly grasped the concepts of synthesis in general and learned how to subtractively synthesis, you'll be able to make your way into the hell world/gold mine that is FM synthesis. It'll take a while though.
I'm not the one to look for for VSTs, I don't use them, but some popular ones are Massive, Sylenth, and FM8. For the love of god, do not get Nexus.
And for DAWs...
Well, if you want an actual, professional level DAW, I'd like to mention the always-present possibility of pirating it. I'm not advocating that you go and do that, really, but it's a possibility. Just don't mention it to anyone or you'll get quite a few disapproving, occasionally elitist and occasionally hypocritical comments coming your way. Such is life.
Oh yeah, get some decent drum samples too. Vengeance is a good place to start (VEC4 is pretty good).
EDIT: Almost forgot this. You should remove the "DJ" part of your name unless you actually can DJ.
btw, the OC thing sounds like a Mary Sue. A
Copy Cat Sue and possibly a
Relationship Sue.
