Pulling hot off three way switch

This forum has been really helpful, so here I am with (I hope) my last electric question or two for this project. Thanks in advance!

I just wired in a set of recessed cans, and I plan to jump a hot line off a three way switch. It is the second in the series, so power feeds the switch ahead of it and the lights it controls come off it. This means there is a neutral in the box to work with, but I'm not sure which, if any, of the switch terminals is always hot so I can attach a jumper to it. Easy formula (common terminal?) or more complicated? Or, worst case, do I need to pull an entirely different feed for these?

Also, in the series of lights, I connected jumpers to all three wires at each unit, but I'm thinking I probably didn't need to do so with the ground. Not that it's a problem, but I may have wasted a wire nut per fixture.

You will need to find another feed. The hot will alternate between the traveler terminals so you do not have a constant hot.

Yeah, that's what I figgered. Luckily there was a receptacle near the first light in the series which was on a circuit with room to grow. A little bit of fishing and I was good to go, everything works like a charm.

One of these days I'll unpack my textbook from my residential electricity class and be able to solve these things myself! Appreciate the input!
