I got the second question answered on mIRC so I will post the answer for anyone who may be interested.
The +2 is a Skill increase so it counts just like a skill point you receive from gaining a level.
Example: If you have a 0 Skill and you get a cybernetic implant you will have a 2 Skill and any subsequent raising would cost Skill points accordingly. In this case 3 more skill points to raise your skill to a 3.
If you were at Skill level 3 and implanted you would have a skill level of 5 and could not go any higher.
The optimum level for implants would be at Skill level 3 as you are getting the most bang for the buck.
Are the skill increases from cybernetics meant to apply to all aspects of the skill? For instance, is the +2 Strength from the arms supposed to affect max carry weight, HPs, and a/e OR is it meant to only affect carry weight?
Vision without action is a daydream. Action without vision is a nightmare.
It upgrades the skill, so everything the skill does. Looks like HP may not be updating correctly right away, but should update on level. Kyle is aware of this; not sure if/when he is going to be fixing it.
