When shooting in low light, should the shutter be bumped to 1/60 to avoid really strong motion blur?
Or just use a faster lens like 1.4?

bumped from what? It should be 1/60 or 1/50 already. Unless you're shooting 60fps, then it should be 1/120.
Of course you can shoot at other shutter speeds, but the slower you go, the more motion blur you will see.

sorry, bumped from 1/50th.... will there be a noticeable difference shooting at 1/60 @ 24p?

From 1/50th to 1/60th? It'll be a little less sensitive and a tiny bit crisper at 1/60th than 1/50th.

I saw in one of your other posts Barry, that to just leave it at 1/60 and just not think about it anymore... would you still recommend that?

Always.
The only reason to change is if you have a specific aesthetic you're trying to accomplish, and you know exactly what you're doing, and you know for certain that the lights you're shooting under won't cause issues.
If you really need a slower shutter speed for more light sensitivity (in the USA) consider 1/40th instead of 1/50th. It should equally avoid the same banding issues.

Will 1/40th work alright with 24P?
What about 24p in a 60i stream (non-patched GH1.)

Yes, it should work fine; I haven't tested it with a DSLR but I tested it with my Red One and it worked fine.
It's a (what, divisor?) of 1/120, so it sync's up with the light's cycle. You can use 1/120, 2/120, 3/120, 4/120, or 5/120... aka 1/120, 1/60, 1/40, 1/30, or 1/24. They all should work equally well, although I'd be a little iffy about trusting 1/120.
And it makes no difference whether you're recording 24pN or 24p-within-60i, as the sensor is running 23.976fps in both cases, and that's what matters.

Seen some great stuff with one of those. A guy at the San Rafael Philip Bloom meetup had a Home Depot LED hand lamp, with an orange gel rubberbanded to it, inside a china ball, and it lit up the dark bar enough for just about everyone to get some great shots...people kept yelling for people with LED light boards and for that guy to "bring that light over here!" I plan on building a couple like that next time I have an outdoor night shoot.
If you're shooting at 24fps , your shutter speed should be 1/50. The only reason you'd set your shutter speed to 1/60, is if you were shooting 30 fps.
The reason for this is that we are attempting to approximate the 180º shutter rule wherein the speed of the shutter should be 2x the frame rate to produce the most filmic result. Unfortunately, the Canon DSLR's don't have a shutter setting of 1/48 (24 x 2), but 1/50 is pretty damn close. In keeping with this rule, when shooting at 60fps, your shutter should be set to 1/120 (60 x 2).

Is this true? I'm shooting at 24 fps @1/60. Footage is looking great to me. Should I back it down to 1/50?

60 shutter speed is fine, so don't worry about it. As a matter of fact 60 would provide a sharper image than 50, but realistically it's impossible to tell the difference. I remember Barry posted some test under certain lighting conditions and suggested that a shutter speed of 60 would prevent some "flickering" that certain users were having. After that many people just always left it on 60 and everything is fine.
