EAD and GC questions

Can I use EAD card to switch job? Same job category, just a bit more money.
Any impact on pending GC? My I485 been pending more than 3 years.Getting really tired waiting.
Also, is it true you have to wait more than 6 months after getting GC to change job?

Many thanks in advance.
