For me, I had the electrodes extending into the weird glass thing from the bottom, which were connected to the battery pack. I then drew the test tubes on top.

Volume before was 2.15, can't remember the others :frown:

For the question about whether or not the volume would be changed due to the air at the bottom of the burette, I said yes.

Yeah, it was 108.96, but I rounded to 109.

Yeah, you got the general gist of it. You need to label the KCl in there though, and I also think the electrodes have to extend into the test tube (can't be 100% sure though).
