You should be just fine. That small adjustment in hours is very small and really no big deal. Most pilots have that. When it comes to neatness of the logbook, it should be somewhat legible. A lot of airline interviewers, from what I have been told, like to see the little mistakes and crossouts because it shows a "working" logbook. If it looks absolutely perfect, it starts to look fishy. And if most of the "chicken scratch" has been done by instructors, I am sure the panel will understand. No worries, good luck!
