Yeah, I use a bucket to hold the first runnings, but just while collecting the wort. As soon as that's done, it goes in the kettle.
As for driving the element, I'm using the third method that Bobby_M mentioned -- regulating the temperature of wort coming out of the RIMS tube. The (very basic) system I'm using now does work, but I am going to spend some time improving it for the build I'm doing now. The current system is prone to overshoot right after ramping up to a high power.
