Tom I want you to think about something. Of ALL the things that can happen, and there is a Sh*t load of things that can happen to screw things up ok. Of ALL the things that happen you, you get a little water from the airlock in the secondary. You are doing an INCREDIBLE JOB. I mean my first batch... man... I did this wrong and that wrong and some more stuff wrong and it still turned out great.
In short... drink more, think less. Stout is an icrecible beer to start with in my opinion. Do a search on haze and you'll see a hell of a lot of first brewers worried about the haze in the beer they just made
Again! Great job
It will come out better then you expect
