Have you tried a filiament guide? I find it works much better.

The most likely cause for the delay is all the plastic oozing out of the melt chamber during warm up and having to be replaced. You need to prime it before the build so the extruder is full. You then shouldn't get more than a few tens of milliseconds delay when you start extruding.

I've ordered two different hobbed bolts (one from a seller on ebay and another from ultimachine) and they were completely different. Both worked, but the bolts were different lengths, the hobbing was in a different spot, and the shape and depth of the grooves was completely different. So ordering another hobbed bolt or two from different suppliers might solve your problem.

As far as the extruder lag goes, in addition to nophead's sage advice, I've also observed a lag between when you click the pronterface button and when the extruder motor moves. If this is what you are experiencing, it hasn't caused me any issues during a real print.
