if you want side markers get celica or rav4 ones. just about any acceory shop will have them for at least one of these 2 cars.
front clear markers can be had on ebay.
ebay again for rear lights (just pay for shipping)
badges.. wtf you want these for? again ebay!
el gauges suck, and luminous dont make camry ones
front bar whats? get an RMM front lip (google)
as for performance, tuning shops and accesoriy shops are the wrong place to go to. you want to go to workshops and mechanics
ive found plenty of places to power up my 3vzfe, from exhasuts to nitrous to turbo (and all the required internals), any decent workshop will help you out. (if you have the v6 though teh first thing you wanna do is get a manual conversion)
also no performance bits for the 2.2? you got the same engien as the previous celica! well.. ok it still sucks, but theres plenty of mods from simple intake and exhasuts to turbo kits for the 5sfe.
