Okay, for the eye colors, load up your neighborhood in simPE, and use sim browser to find a sim who has the eye color you want.
IE, use Daniel Pleasant if you want to give your sim green eyes.
On their page, click on 'More', and choose 'Sim DNA'
And then load the sim you want to change the eye color of, and paste the code into the same place on there's.
Also, how do you mean make your own orphans?
If you're meaning making children in a family, and then using mods to put them up for adoption, then no, they'll just get adopted like regular kids. I used that method back when I played TS2.
