Customizing a Scion Tc ?

Hi. I am a soldier in Afghan right now. I am looking into cuztomizing my Scion Tc. I would like to get halo lights, new rims, chrome grills and lambo doors. I live in the 92310 area. I was trying to see what ya would recommend me getting for the Scion, what websites to check out and what place around that area I kind trust with instalating the lamdo doors ? Thank you.
