PW doesn't support the 600EX-RT yet, though they will at some point. So right now, the ST-E3 or another 600EX-RT are your best bets. Not sure about other 3rd party wireless triggers.
If you have a 7D, 60D it can be optically triggered by the popup flash. A 580 or ST-E2 would also be able to optically trigger the 600EX-RT.
Does the Yongnuo RF-603 has TTL? If not, should I get one of those Sekonic L-358 Flash Master?or If I get two 600EX-RT, can it trigger remotely to each other ?
...I have three 600-RTs and the ST-E3-RT on order, but I decided that using one of them to trigger is a waste....

I have two 600rt units and the st-e3-rt, expensive set up, but it's slick!

No, but I might pick up another 600. I had two 430s that I sold with my 580 and 50/1.4 to help cover the two 600s and st-e3-rt. The 430s were great, but the lower power and lower re-sale value have sealed the deal of, go big or go home.
