I just got the Ratings txt file from the draft project. Most are self explanatory eg. FGPBASE = FG rating, OREABILITY = Offensive Rebound rating, etc. BALABILITY is the passing rating, just copy these over when you create the players. Ignore the OVR rating. Just do the ratings that you can edit in create-a-player.
Also there is a appearance file you can use for appearances. You will probably just need the heights (they are in inches, eg. 72 = 6ft, 78 = 6"6), weights and skin colors (0 Lightest - 4 Darkest).
As for the faces, I guess you just look up pics of the player and do as best you can.
Here are the files with the info in them.

There will not be Player names but rather PLYRPKG's that are the first 2 letters of a players name and first 5 of their last name, eg. KEDURAN = Kevin Durant, GRODEN_ = Greg Oden. I guess just go onto
www.nbadraft.net or
www.draftexpress.com and check their mock drafts and follow their lead, just make everyone starting at the top and work your way down, skipping any players you cant find in the files containing the info.
Good luck.
