Yes, to both, but I'm not sure where to tell you to find them off the top off my head. Hopefully someone will be able to point you in the right direction.
Edit: look for inge's stay-things shrub

For changing the skintone of a sim, there's two ways: You can go to the sims2graveyard (google is your friend if you don't know where it is) and download the custom skintone selector, but it's a mod that is no longer supported, so you would be doing so at your own risk. Your other option is to use SimPE by following the tutorial
here. However, having said that, if you have BV then you'll have to wait for SimPE to be updated before doing it.
