it says you have lowered the SVT? If so, did you use the stock struts to lower? If thats the case them im going to have to rule out a new strut in the back, and the others probably arent in that good of shape as it is. I would seriously suggest a new suspension if you lowered on stock struts. It also is very possible you need new sway bar end-links and bushings back there, its common for them to fail.
As for the sound in the front... Sound a lot like a wheel bearing as you pinpointed.
