I'd probably skim thru the Language Reference and Phobos.  After 
that I would practice using Ranges and get a better grasp on the 
functions in std.algorithms.  std.algorithm has some good stuff 
for dealing with data.  Since you want to do Network programming 
I would suggest Vibe.d and read thru the source of it.  Also 
whatever DB you normally use check out the projects for those 
drivers and maybe contribute as some need ppl.  Since you say you 
want to become "hardcore" I would suggest porting some popular 
libraries over to D.  After that maybe look to get involved in 
Phobos and/or the compiler of your choosing.
