The HP bonus is just a one-time thing and is fairly useless. Perception is also not a very strong skill (a set of macrobinoculars is significantly more powerful). It could be argued that the force % and race multiplier make it overpowered, but for comparison you have only to look at a race such as Noghri or Wookiee and you will find that their skills and race multiplier are significantly superior.
It is true, however, that the races are not particularly "normalized," but there have been many efforts at fixing this in the past and it tends to be vetoed in the end or otherwise stalled. But Gand are far from the more severe example (although to a certain degree it does also depend on your personal subjective ranking of traits, which certainly varies as it should).
