Yep no doubt as said previously by others, this is all you need:
Quickpar
Winrar
Astraweb or giganews
NZB Matrix (nzb search files) the best imo
Vlc player
I probably missed something but this is what i use and it's fantastic
(As also said before, don't forget to use 20 connections and ssl)
Hope this helps, any further questions don't hesitate to pm
