There aren't too many second gen owners here on the forum. However, there's quite a few on the FB page. You could try checking there (link in my signature). Outside of that, junkyard for some of those is best bet.
Fog lights and headlight housings are likely cheap in a junkyard. There's a few options for lowering springs. TRD, Tein, Canuck, to name a few. You'll likely have a hard time finding the strut tower brace for an 09/10. Not sure if they made an upgraded rear sway bar.
Good luck in your search, and post some pics if you do lower it or things of that sort.
