The differences look pretty substantial, especially the new steering damper and new black color!

New for 2008:
  • New piston with 13.1:1 compression ratio
  • New cylinder head porting for improved power
  • New lighter-weight valve train components raise rev limit to 13,500 rpm
  • New lighter counterbalancer shaft and drive gears.
  • New exhaust system for more power
  • New camshaft timing for added power
  • Revised carburetor jetting gives smooth power delivery under all riding conditions
  • Engine torque now reaches maximum at 8500 rpm.
  • New clutch features judder spring for smother engagement.
  • New Honda Progressive Steering Damper (HPSD). Tested by Team Honda, this lightweight, compact steering damper improves cornering ability and reduces rider fatigue.
  • New fork triple clamps with 22mm offset for improved cornering.
  • New Showa fork features a larger cartridge rod and new cartridge oil piston for improved oil flow and less friction, plus stiffer springs for improved mid-stroke action.
  • New rear shock valving matches changes to the fork.
  • New works-style front and rear brake discs reduce unsprung weight.
  • New rear fender shape for improved mud protection
  • New larger left-side engine guard
  • New black color (2008 special color)

Not easily. The top part of the HPSD steering damper mounts to a boss on the frame. If you changed out the bottom triple clamp and welded a boss to the '07 frame, then I would think it could be added. It's probably a lot cheaper just to add an aftermarket unit though. I'll be posting something on the new damper here in a few minutes.
