deathgurad, i hate them. Welcome anyway.
Aww, c'mon man, be a little bit more welcoming. Sorry pand, but you should post this in the 40k section, this place is more for welcoming new members. Of course, you're a new member, but you've already had an intro, so you'd get a lot more feedback if this is in the 40k section.
But to help you a bit, here's my 2 cents. I would get a defiler and a vindicator as vehicles, and maybe a land raider, all for fire support. A dread may be nice, but the defiler may be a better choice. If, however, you are getting dreads, get the FW one, the GW one looks terrible. At FW, you can choose which dread you want, Khorne, Iron Warriors, Death Guard, etc. And if you've got money, you can even buy the conversion packs FW sells.

Good luck on your Death Guard!
