Wesh; seeing as everyone else is ignoring ya, heres some help:
The reason u r seeing 600 unconfirmed transactions is that u are currently on a fork of the blockchain. This is not good...
Look at my last block:

69664      4747512364439223888      dinsdag 18 februari 2014 22:50:06   
      
      1      49 + 1      128 B   
      
      2      12965468926053797053      70 %   
   

If none of that matches with what u r seeing, shut down NRS, delete everything and re-install. U need to be running version 7.4 or 7.5, available from the first page of this thread.
Install, run, let the blockchain update and then u can log back in to start forging.
Hate to tell u, but u will need to have at the very least 10,000 NXT (preferably a lot more) to see any forging income at all.
