You can find light wheels for much less than that but you may not like the styling and you have to be careful. Cheap, durable and lightweight usually don't go together. You can pick two and find what you want easy, though.
Motegi wheels have a reputation for not being very durable but a set of Traklites at 16 lbs and 100$ a wheel have done fine for me. That's 4-5lb lighter per wheel pre-facelift. I don't know the weight on the '17s. Of course if you're running a short sidewall or smacking potholes all day, you might not have the same luck.
Any suspension or chassis changes need to be done with a specific objective in mind. As has been said, the stock setup is pretty good. If I remember correctly the TRD "lowering kit" is just springs. What do you want to change about the handling of the car? If you just want a direct increase in cornering ability, tires are where you should be looking. To get much out of suspension upgrades, your parts need to be adjustable and you need the opportunity and experience to tune them. If you don't already know what you want the car to do differently and how to do it, messing with the suspension parts usually does more harm than good.
I'd look up lots of suspension tuning tutorials and take your car to an auto cross school or HPDE if you really want to sharpen up your car's handling. Then you can get a feel for how the car acts at the limit so you know what you want it to do differently.
As for bodywork, I guarantee there are parts coming down the pipe. They're going to be expensive though. I'd watch C West. They make some pretty tasteful parts for the pre-facelift twins.
