I've been reading a lot of previous posts and it seems like 3-4% is normal. Hopefully someone with experience will chime in since I'm currently sitting at 3" lift and would also like to know before experimenting any further.

There is no set pinion angle for a specified height. All lifts will yeild different heights depending on vehicle weight which will lead to slightly different pinion angles to have the pinion pointed right at the transfer case.

When adjusting the control arms, I know it will throw off caster. Search for how to do an at home alignment and you will find tons of information regarding this.
