For the trim it's hard to find and when you do it's expensive I suggest trying your local Toyota dealership. The side mirrors you should look at a junk yard or the Toyota dealership as well. I bought mine from the junk yard last year as one of mine was broken in half when I purchased the car. For the rear bumper I suggest that you do a search on google or go to ebay motors and also trying these web sites
www.duraflexbodykits.com and
www.horsepowerfreaks.com <---this one also sells a lot of performance and factory parts for our cars. You might find your original rear bumper or something better that you might like. For the hood struts you can purchase them off the horsepowerfreaks website or you can check around your local parts stores for these. As far as the door handles and spoiler you can look around on the web and at the dealership as well. Let me know if you need any more help
