Good advice so far. Pay close attention to the stuff sidewaysducati posted in his second reply.
For a big guy on a 600, you need to pay close attention when carrying a passenger. By yourself, you load the bike pretty good. You may want to break out the tape measure and record some suspension settings (preload mostly) for riding with a passenger. This will help keep the chassis most sorted for the amount of weight. As you go along, you can adjust your damping settings to your tastes. If you keep track of "alone" and "passenger" settings, you should have no problem with the suspension running out.
As far as power goes, I can't help. Both my bikes are 1000s, and I have an absolute no passenger policy on the YZF. On the FZR, once I have the suspension set for a passenger, I generally can't tell they are there, but I know that I unconsciously adjust my riding.
Hope this helps....
