48" bulb on a 54" tank is absolutely fine IMO.
It's only 3" on either side, some of which could be occupied by the perimeter of your hood if you are building one, so its nice to have a little space.
You could also consider putting the Kessils closer to the ends, in the 4 corners pointed towards center a bit, that way you get a bit of LED on that short end wall. See drawing below.
Ya I would start another thread like a build journal, that's what I'm doing, then you can discuss the multiple topics in one thread easier, although certain things might get more exposure in specific threads.
