if you treed him twice and bayed him once on your first bobcat hunt, you are doing mighty good. Just hunt when ever you can, day or night if it is legal there. Just get your dogs on as many bobcat tracks as you can, as often as you can.
I am not sure what you mean about a dog coming in to a tree late. Do you mean there is already a dog treeing, and then another dog came in to the tree, and at that point the cat bailed out so the race continued on? If that is the case, it is hard for me to comment, as I have not had cats bail very much. I think it is a regional difference. If I heard that happen, I would be searching my memory to see if the first dog had ever false treed on me. If it had, I might be thinking the second one came in there and showed the first one where the track had gone so they could continue on as they should. It is very hard to judge without hearing the race myself and without knowing the style, strengths and weaknesses of the dogs involved.
My experience with a second dog joining in on a bay-up is that it makes things more solid if the dogs click together at all.
As far as water goes. Our water is very hard durring cat season, and streams are highways for all kinds of game including bobcats. But hopefully Mr Clay and others will have some comments on the water cats.
I'll make a suggestion for you on getting help

If you ask for pros to comment, you probably will not get too many responses since me and Tim are the only pros on here. (Actually I dont know how I could be a pro since my real name is Hanah and I have never been bobcat hunting a day in my life.

Amazing how much I have learned from you all.)
