Okay well does anyone know where I can go to get help?
I couldn't tell you much about pvp, and don't have a dm stalker. My first 50 was a DM/Regen scrap, so I can give moderately good advice there.
Take Siphon Life at 8 and frankenslot. If you click the DM guide in my sig you'll find some REALLY good slotting given by some of the best in the scrapper forum to get the most out of it.
If you're comfortable with lining up cones then you'll like Shadow Maul. Bear in mind, however, that it has no place in the higher dps chains of SM-SL-SM-MG and the lower recharge chain that uses those three along with SP (I can't remember what it is at the moment).
Speaking of recharge. You're going to want a lot of it. And a slow resist IO from the Winter's Gift set.
Help for pvp would best be found in the pvp forums. They're not that scary once you get to know them.

I need help with a legit PvP and PvE build. I'm mostly going to use him for PvP. I just need help with what to pick up and what IOs to put in. Any help is greatly appreciated.
