Dynamat or other sound deadener will help with rattles and road noise. Apply to the trunk before installing the box will make a difference.
I really like the GS with the box between the shock towers. Speakers facing the back bumper and a port thru the factory location.

im running 2 jl 12s with a 600 watt amp. sealed box between the towers. amp has adjustable bass gain control from the cabin, which is key because adjusting the bass at the wheel is crucial. i am happy with the sound, but new rattles can drive you crazy sometimes. you just got to hunt them out. hope i helped, good luck

Heh heh yeah I run a 1800x1 RMS... it just *makes* rattles. After a while, all kinds of parts have been bounced and moved that much that they don't quite fit together right any more, and they rattle. Kind of a whole car rattly squeeky deal. Needless to say, the amp is for sale and not going into the Lexus! And yes, with that kind of power, bass control from up front is essential if you want to keep your hearing or licence.
The sound deadening mat will be needed, but there are a few other methods to attacking rattles. Expanding foam can be great for filling empty space between sheet metal, like inside the trunk lid, that sort of thing; just be real careful not to overfill (since it does expand a fair amount) and put plastic or something down so you don't get it on the car or trunk. Also, if you can find sheets of soft, open-cell polyurethane foam about 1/4" thick, that works well to put behind or between panels that rattle together to isolate them.

Be real careful with the expanding foam. Pick one that expands the least and use just a little of it. Foams can bend metal and crack plastic easily when they expand.
As for rattles, Lexus is a fairly well sounddeadened car. After you install your subs you will know whether you need sounddeadening or not.

future, I have a pair of Kicker Comp 10's in a bandpass enclosure being pushed by a Kicker 700.5. It's not a ton of power, and there is a minor license plate rattle at higher spl. The quality of construction of the GS surely absorbs a great deal of noise. Sound damping material would be a good idea though.
As for speaker placement/direction, what my installer found was that the subs facing backwards gave the best output.......and definitely remove the stock sub to allow the subs output to be ported into the cabin. Good luck!!!!

The license plate is a prime candidate for the other foam I mentioned. I don't know where you'd be able to find it, maybe a craft store; I get it from work.
If this picture works, here's what the foam looks like on the back of a license plate.
