Haven't listened, will listen later or tomorrow (have to conserve bandwidth, 15gb/month is NOT ENOUGH).
But, for clean vocals, a bit of compression so that there's not too much dynamics. Then a saturator (I use PSP MixSaturator2) going as strong as you can without making it overly distorted or bringing out too much room sound, then a nice verb. And autotune helps slot it in nicely too. But the saturator is the key point, it really brings out the slight distortion some vocalists have around 3khz which makes the vocals just pop out of the mix perfectly while not being too loud.
