I can't answer everything here (hoping one of the other ladies can help!) but I have done a lot of research and am working with an electrolycist myself, so maybe I can help answer some of these...

1) Regardless of how much I drink or moisturize the night/morning before we seldom see loads of lye coming out, apparently my electro person can see the lye making the skin bulge but it doesn't come out very much at all.
This is almost undoubtedly a good thing.  The lye is needed to kill the follicle.  If too much is produced and comes out onto the skin, skin irritation will be the result.  Lye is extremely caustic and will burn tissue and even cause scarring.  Best to keep it where it is needed. 🙂

2) Sometimes I can hear fizzing on some hairs and those hairs seem to come out with very little tugging when tweezing but by and large the tweezing tugs a lot to the point where I can see my skin being pulled toward the tweezers and it basically feels like the hairs are being plucked not released from a successful electro. The tweezing hurts so much more than the electro itself.
This often happens when the follicle is curved, so the needle is unable to reach the base of it directly.  Over time (more than one session, generally) these can be killed, but because it is indirect there will most likely need to be more than one treatment for this kind of follicle.

3) My electro person seems to always move the needle up and down slightly for almost the entire duration of the 10 seconds zap. When I inquired it was suggested that this was to help the lye move and form but when working with a none insulated needle it seems to me there is no need to move the needle around and the point would be to get the needle right down on the root for the entire 10 seconds?
You've got me on this one... mine uses galvanic with fifteen needles at once.  The zaps are longer, but possibly lower in intensity.  Still, the needle, once seated, stays in place during my treatments, anyway.

4) Sometimes when the needle is stuck in me it feels like it's pushing through skin rather than being put down a hole that is already there.
This seems to be fairly common, and can be related to curved follicles that are being forced to straighten by the straight needle, and also can be caused by nerves located very close to the follicle itself.
Hope I was able to be of some help to you... I'm sure others will have more input. 🙂
