FJ TRD Anthracite Rims?

Hey Guys, first time poster to the board here. I have recently fallen in love with the 16" FJ TRD anthracite 6 spokes and after perusing these boards for days trying to find information about them i thought i'd sign up and ask you guys the questions i have. I just called my local dealer and he is trying to find some for me but i really doubt he will be able to.

So here goes, Is there anyway i can find these in Canada or in the States and have them shipped? and if i cant find them should i just get the silver ones and have them painted?

Are there any problems/ issues with these rims on the Tacoma, and what is the biggest set of rubbers i can throw on these without lifting the truck?

Also, what would look better on my Metallic Gray TRD, the anthracites or the black ones?

Thanks
